They are a scam. I have paid $200 for a TV stand and received nothing. When I contacted AliExpress, they said seller has shown proof that it was delivered. However, the item was not delivered to my home. The picture that FedEx had on tracking site shows a house that is clearly not my home. I have provided both screenshot from FedEx tracking and my home picture, but AliExpress disregard my proof and still gave my money to the seller. AliExpress said they will only take a signed statement from FedEx stating the item was not shipped to my home. I have asked FedEx and they refused to provide such statement because I am not the shipper. AliExpress site has tons of people with similar experiences and end up lose money to the site. There purchase guarantee means nothing because the whole site is a scam. I will never buy anything from this site again.
