I recently attempted to purchase an item from one of their suppliers. I was told by the supplier it had been shipped. After waiting and not getting the item, I contacted AliExpress and started my protection claim. The supplier insisted they sent the item, but would send a replacement if I would have AliExpress release the purchase funds. When I refused to do so AliExpress gave me a full refund. I can not speak highly enough of AliExpress' Buyer protection. They have you protected!
