Everything is sold in bulk, most things a very low quality or fake. They aren`t like amazon who take a cut from the product, they only earn money through advertisements and stuff like that. There good products there but everything is sold directly to the buyer, mostly in bulk orders which bring down the cost a lot.
There a bunch of disgusting chinese fakes. I doubt you would find a good seller on there . I ordered a pair of red roshies and they sent me blue knock offs. The shipping takes like a month. -15/10, AliExpress is a pos website with pos scamming chinese merchants that will try everything in their power NOT to give u a refund.
