If your order hasn't shipped yet, it may be possible to cancel your order.
To attempt to cancel your order during processing:
If it is still possible to submit a cancellation request, you will see the Request Cancellation button on the Order Details page.
Clicking this button will send a request to cancel your order, but it does not guarantee that your order will be canceled. If the order is already far along in the processing stage then it will continue to be shipped.
If you have changed your mind about the order and it is too late to cancel, you can return any unwanted items in accordance with the seller's returns policy.
