I have paid on AliExpress via PayPal on AliExpress website and they accept PayPal, this seller accepted PayPal, because i paid numerous times. And what exactly is hard to understand for you i don't understand. I wrote that i bought from AliExpress website 5 items and they closed all my orders, i paid one via PayPal on AliExpress website and paid for others with credit card and they closed all my orders and i asked for help here, because they aren't answering and thought somebody had such issue and can help me but i see, that here isn't much better.
