Yes, ASDA normally allows you to amend an online grocery order after checkout, provided you make the changes before the amendment cut-off shown in Your Orders.
ASDA currently says grocery orders can generally be changed until 11pm on the night before delivery or collection. You may be able to add or remove products, change quantities and update substitution preferences.
However, temporary website and app restrictions may prevent customers from changing a confirmed delivery slot, delivery address or collection store. The options shown against your individual order are the best indication of what can currently be amended.
How late can you amend an ASDA grocery order?
ASDA’s general amendment deadline is 11pm on the night before the order is due.
For example, an order due on Friday would normally need to be amended and checked out again by 11pm on Thursday.
The exact cut-off should be displayed in Your Orders. Check this rather than relying solely on the general deadline, particularly during busy periods or when using a different type of delivery service.
You can read ASDA’s current instructions on its official ASDA order amendment page.
Once the cut-off has passed, the store may already be preparing the order. At that stage, you will usually be unable to add products or make further changes online.
How to amend an ASDA order
To change a confirmed grocery order:
- Sign in to your ASDA account.
- Open Your Orders.
- Find the relevant delivery or collection order.
- Select the option to amend or edit it.
- Add, remove or change the required products.
- Review your substitutions and quantities.
- Continue to checkout.
- Confirm the amended order before the displayed deadline.
- Check that the order appears as confirmed in Your Orders.
Opening an order for amendment is not enough on its own. You must complete the checkout process again so ASDA saves the changes.
The available controls form part of the ASDA online shopping process and may look slightly different in the website and mobile app.
What can you change after checkout?
Depending on the options currently available for your order, you may be able to change several parts of the shop.
Add more products
You can normally add groceries until the amendment deadline.
Search for the required products, add them to your trolley and complete checkout again. The total shown for the order should update to include the additional items.
Adding a product does not guarantee that it will be available when the store picks the order. It may still be substituted or removed if it is out of stock.
Remove products
You can usually remove items that you no longer need before the cut-off.
Check that the quantity has changed to zero or that the product no longer appears in the amended trolley before confirming the order.
Removing an item may affect:
- Multibuy savings
- Minimum-spend promotions
- ASDA Rewards Missions
- Delivery or collection eligibility
- Promotional codes
- The estimated order total
Review the complete order rather than checking only the removed product.
Change quantities
You may be able to increase or decrease the quantity of an existing product.
Make sure the revised quantity is saved before returning to checkout. Products with purchasing limits may not allow you to increase the number beyond the amount ASDA currently permits.
Change substitution preferences
ASDA normally lets customers decide whether unavailable products can be replaced with alternatives.
When amending the order, check whether you can:
- Allow substitutions for a product
- Turn substitutions off for a product
- Change the preference for the whole order
- Add product-specific notes where available
Turning substitutions off can prevent an unwanted replacement, but it may mean the product is removed entirely when unavailable.
The treatment of unavailable and replacement products is covered by the ASDA returns, refunds and substitutions process.
Add or remove delivery instructions
If the order page provides an instruction field, you may be able to update useful information for the driver.
This could include:
- The correct entrance
- A gate or building access instruction
- Directions to a difficult-to-find property
- Information about a doorbell
- A request to call on arrival
Do not include payment information, passwords or unnecessary personal details.
Can you change an ASDA delivery slot after checkout?
ASDA’s general order guidance has previously included the option to change a delivery or collection date and time before the amendment deadline.
However, ASDA has also introduced temporary website and app restrictions under which customers may be unable to change a confirmed delivery or collection slot.
Check the options displayed in Your Orders. If there is no slot-change option, you may need to keep the existing booking or cancel the order and place it again.
Cancelling and reordering carries a risk that:
- The original slot will be released
- Another suitable slot will not be available
- Product prices will change
- Promotions will end
- Some products will become unavailable
- A new payment authorisation will be requested
Do not cancel a confirmed order until you have considered whether losing the slot would cause a problem.
Can you change the delivery address?
ASDA may not allow you to change the delivery address after an order has been confirmed.
This restriction helps prevent an order from being moved to a postcode served by another store or fulfilment location. Delivery availability, charges and product ranges can differ by address.
If the saved address is wrong:
- Check whether an edit option appears in Your Orders.
- Do not assume that changing the default account address will update an existing order.
- Contact ASDA before the amendment cut-off.
- Ask whether the order must be cancelled and placed again.
- Confirm what will happen to the original slot and payment authorisation.
Do not leave the order active when it is booked for an address where nobody can receive it.
Can you change the ASDA collection store?
ASDA may prevent customers from changing the collection location after checkout.
A different collection store may use separate stock, appointment capacity and picking arrangements. Changing it can therefore require a new booking rather than a simple order amendment.
If you selected the wrong location, check whether the order can be cancelled and replaced. Make sure another collection appointment is available before giving up a suitable confirmed slot.
Can you switch between delivery and click and collect?
You may not be able to convert a confirmed home delivery into a collection order, or a collection booking into home delivery.
The two services use different appointment capacity and fulfilment arrangements. You may need to cancel the existing order and book a new one using the preferred method.
Choosing ASDA click and collect may provide more appointment options when home delivery slots are unavailable, but the original booking will not necessarily transfer automatically.
Do you have to check out again after amending?
Yes. After changing the trolley, continue through checkout and confirm the amended order.
If you leave without completing checkout:
- New products may not be added
- Removed products may remain on the order
- Quantity changes may not be saved
- Substitution preferences may stay unchanged
- The original order may continue as previously confirmed
Return to Your Orders afterwards and check that the updated products, total and confirmation status are correct.
Look for a new confirmation email, although the order shown in your account is more useful when an email is delayed.
Will amending an ASDA order affect the delivery slot?
Adding or removing ordinary products should not normally remove an existing slot, provided you complete the amendment correctly before the cut-off.
However, the slot could be affected if you:
- Attempt to change the delivery date or time
- Change the delivery method
- Switch the address
- Select another collection location
- Cancel instead of amending
- Allow the amendment session to expire
- Encounter a website or app error
Check that the original delivery or collection time still appears before confirming the amended order.
Can adding products cause ASDA to cancel the order?
Adding ordinary groceries should not normally cause the complete order to be cancelled.
However, the amended order still needs to pass ASDA’s checkout, payment and fulfilment checks. A problem could arise if:
- The payment method cannot cover the new estimated total
- The card has expired
- The amendment is not confirmed properly
- The order no longer meets a required condition
- A technical error occurs
- The revised basket exceeds a product or order limit
Make sure there is enough money available for the updated order value and check that the order remains confirmed.
Will ASDA take another payment when you amend?
ASDA may update or request a payment authorisation based on the new estimated order total.
This does not necessarily mean you have been charged twice.
When you add products, the amount reserved by the bank may increase. When you remove products, the final completed payment may be lower than the original estimate.
Your account could temporarily show:
- The original pending authorisation
- A revised pending amount
- More than one temporary payment entry
- A lower final completed charge
- A released payment hold
ASDA should ultimately take the final amount due for the completed order. Your bank controls how temporary authorisations are displayed and when released money becomes available again.
What happens to prices when you amend an order?
The amended order may use the prices and promotions applicable under ASDA’s current checkout rules.
Check the updated total carefully because:
- A promotion may have ended
- A product price may have changed
- A multibuy may no longer qualify
- An additional item may activate an offer
- A removed item may reduce a saving
- A substitute may later affect the final total
Do not assume every product will remain at the price displayed when the original order was placed.
The final receipt may also differ from the amended estimate because of unavailable products, substitutions and weighed groceries.
Can amending affect ASDA Rewards?
Yes. Changes to the products or order value can affect ASDA Rewards earnings.
Adding or removing products may change progress towards:
- A Mission
- A Star Product reward
- A spend-based offer
- A product-specific Cashpot promotion
Check that the amended basket still meets the applicable terms.
Rewards are generally based on the qualifying products ultimately purchased, not merely the items that appeared in the trolley before delivery.
Can you use a new voucher when amending?
You may be able to add, remove or replace a voucher during the amended checkout, depending on the voucher conditions and the options shown.
A code may fail because:
- It was already applied to the order
- The revised spend is below the minimum
- An eligible product was removed
- The voucher has expired
- The offer cannot be combined with another discount
- The code does not apply to the delivery method
- The amendment is being made after the promotional period
Check that the discount appears in the new order summary before confirming.
Do not assume a removed voucher will automatically return to your account or remain valid for another order.
Why is the amend button missing?
The option may not appear because:
- The amendment cut-off has passed
- The store has started preparing the order
- The order is already on its way
- The order has been cancelled
- A previous amendment session is still open
- The website or app is experiencing a problem
- The order was placed through a third-party service
- The type of change is currently restricted
Refresh Your Orders and check the delivery date and current status.
You can also:
- Sign out of your account.
- Close and reopen the browser or app.
- Sign back in.
- Try the ASDA website instead of the app.
- Update the app.
- Try another browser or device.
Contact ASDA if the cut-off has not passed but the amendment option remains unavailable.
What happens if the amendment fails?
Do not assume the revised shop has been saved.
Open Your Orders and check:
- Whether the order is still confirmed
- The products and quantities listed
- The estimated total
- The delivery or collection slot
- The substitution settings
- Whether another checkout is still required
Take a screenshot of any error message.
If the original order remains confirmed, ASDA may still supply the earlier version of the trolley. Contact customer services when an important amendment has failed and the deadline is approaching.
Can you amend an order after 11pm?
Normally, no. Once the amendment deadline passes, ASDA may begin preparing the order.
Customer services are unlikely to be able to add individual products manually after picking has started.
When you need an extra item urgently, your alternatives may include:
- Buying it in store
- Placing a separate rapid delivery order
- Using another local grocery service
- Collecting it separately
- Ordering it with a future shop
A separate order will have its own prices, availability, minimum requirements and charges.
Can the driver remove an unwanted product?
The driver cannot normally amend the original online trolley, but you may be able to reject an unsuitable substitute or unacceptable product during the handover.
Tell the driver before the product is handed over completely and check that the rejection is recorded.
Rejecting an item at the door is different from removing it before the amendment deadline. The final charge or refund treatment may therefore differ.
Do not expect the driver to add a forgotten product or replace an unwanted item with something else from the vehicle.
Should you cancel and reorder instead?
Cancellation may be necessary when you need to change something that the amendment system does not permit, such as the delivery address or collection store.
Before cancelling, check:
- Whether another suitable slot is available
- Whether current prices are different
- Whether promotions are still active
- Whether the original trolley can be reordered
- Whether a payment authorisation is pending
- Whether the order is still within the cancellation period
Cancelling can create more problems than keeping the order and buying one forgotten product separately, particularly when delivery slots are limited.
When should you contact ASDA?
Contact ASDA when:
- The amendment button is missing before the cut-off
- The amended products were not saved
- The order lost its confirmed status
- Your delivery slot changed unexpectedly
- You selected the wrong address or collection store
- The website displays an error
- The payment authorisation appears incorrect
- You cannot tell whether the original or amended trolley will be supplied
- You need to cancel but the option is unavailable
Provide the order number, delivery or collection date, amendment deadline and details of the change you attempted.
ASDA can check the status of the order, but it may not be able to make changes once the store has started preparing it.
Frequently asked questions
Can I add one forgotten item to an ASDA order?
Yes, provided the amendment option remains available and the cut-off has not passed. Add the product and complete checkout again to save the change.
Does opening an ASDA order for amendment cancel it?
It should not cancel the order by itself. However, you must complete the amendment correctly and confirm that the order still appears in Your Orders.
Can I amend an ASDA order on the delivery day?
Usually not. ASDA’s general amendment deadline is 11pm on the night before the order is due, although you should follow the deadline displayed for your booking.
Why can I change products but not the delivery slot?
ASDA may temporarily restrict changes to confirmed slots, addresses and collection stores while still allowing customers to edit the products in their trolley.
Will I lose my ASDA slot if I amend the basket?
Ordinary product changes should not normally remove the slot. Check the booking details before confirming, particularly if you attempt to change the date, time, address or fulfilment method.
