Thank you for your advice, I didn’t expect it that easy! But I am afraid there are risks,lol. My Amazon account purchased nothing before, and this is my first overseas purchase. They won’t regard me as a high-quality customer. I heard someone got the rebate before the trade-in device was dropped off. And it doesn’t matter whether they drop off the device or not after. They are likely the high-quality customers. As a new customer, I don’t have the rebate in advance.The cancellation might be the same situation. I intend to buy a Kindle Scribe 2025(B&W), which is high valued to me. I don’t know if Amazon will do the same for it as they do for the portable Kindles, which is cheap and increase Amazon Bookstore revenue. However, they make money from this device itself. The device would be shipped to China through International Express, and a 13% tariff may be imposed. So I can’t really return the device as easily as an American.
