This article explains whether you can cancel or change an order after placing it, and what your options are before and after that point.

Not once it's placed — there's no self-serve cancel button for a placed order. If you need to cancel, contact support through the messenger on this help center or in the app, and include your order number and the reason you'd like to cancel. Support will let you know whether cancellation is still possible depending on how far the order has moved into fulfillment.

This is the one case where you can change things yourself. Before you claim a reward, if your sender has enabled it, you can swap it for a different product or convert it to balance instead. This is the fastest way to fix "I don't want this" or "I'd rather have something else" — look for the swap or convert-to-balance option on the reward page before you complete checkout. Once you've claimed and placed the order, this option is no longer available.

Changes to a placed order — like swapping the item, changing the quantity, or fixing an address — aren't self-serve. Contact support with your order number and what you'd like changed. Whether it can be done depends on whether the order has already entered fulfillment or shipped.

If an Amazon order becomes unavailable or is rejected after you place it, it's automatically refunded and you'll receive an email confirming the refund. You don't need to contact support for this — it happens automatically.

Contact support as soon as possible. The earlier you reach out, the more likely your order can still be cancelled or changed before it ships. Include your order number and what you'd like to happen, and support will confirm what's possible.
