The application steps are as follows:

1. There is a word "help" on the top of Amazon's homepage. Click to enter the help interface, and then click to contact us.

2. Immediately log in to your Amazon account. The page will pop up the latest order information, and then click to select the order for which you need to apply for price protection.

3. Select the reason.

4. Click chat to start a conversation with customer service. This step requires applicants to have a certain level of English communication ability, because online communication is often the fastest way to solve the problem. Try to choose this method to communicate with customer service in English to solve the problem, or you can use Chinese English, which customer service can basically understand.

5. During the chat process, you need to have a conversation to make up the difference. You need to provide the name information of your original product, the purchase price of the original product and the latest price after the update. Customer service will make price compensation based on these three pieces of information.

The way to compensate for the price is to return the difference to the bank card used when placing the order, which will generally be credited within 3 to 10 working days.
