The process is as follows:

1. Click Return at the order page, select I want to return, select the reason for return, print the return label, wrap the returned goods, and hand them over to the courier together with the return label.

2. If you choose to pick up the goods yourself, you need to make an appointment on the Amazon Global Shopping Return Self-Pickup Service page, and go there according to the appointment time and location.

3. The returned goods must be consistent with the information displayed on the order page. If the goods are not damaged, missing, used, etc., and within 30 days from the date of shipment, the postage will be waived.

I hope the above information helps answer your questions.
