You can log in to the Amazon official website or mobile client, find the "My Orders" page, select the order that needs a refund, and then click the "Apply for Refund" button.

Then follow the system prompts, fill out the refund application form and select the reason for the refund, and finally submit the application. If the product you purchased meets the refund conditions, Amazon will return the refund to the original payment method after receiving the return and confirming that it is correct. It should be noted that different products may have different refund policies. It is recommended to read the relevant policy regulations carefully before applying for a refund.
