My explanation: If you use the credit cards of major domestic banks, although they are also VISA or MasterCard, Amazon will review the issuing place, and as long as it does not meet the company policy, it will not deliver the goods. Changing an American card should solve the problem. I don't know what kind of goods you bought, but for example, you can't use a domestic card to buy mp3 or American kindle e-book content, even if you can pay in foreign currency.
Sometimes Amazon will review the ip address of the computer that placed the order. If it is inconsistent with the country where the service is located (such as China's visit to Amazon, USA), some goods will be refused to be sold, and vice versa.
Complete solution: 1, meter wall; 2. Use the credit card of the host country at the same time.
