First, you need an eBay ID. Second, you need a PayPal ID to pay. Now you can use UnionPay. Third, it is similar to Taobao. But you must remember the following. a. eBay usually contacts through email, that is, internal messages on the site. eBay does not accept private chats under normal circumstances. b. It depends on where the seller will ship. Many American or British sellers do not ship to China. Chinese sellers do not ship to China even more. c. Pay attention to tariffs. Because if tariffs or customs detain goods, even if you give a bad review, it can be deleted. d. Pay attention to the logistics method. It is best to have registered mail. But it is more expensive. eBay generally evaluates sellers based on logistics issues. This is also a problem that eBay has never been able to solve. Finally, you must remember that eBay reviews can be given within 60 days from the time you click on the purchase. If you want to seek compensation, you must open an eBay case within 45 days of payment. After the case is opened, the seller has 10 days to deal with it. If you have any problems, it is best not to open a PayPal case because it is very slow (resolution time).
