iPhones — iPhone scam
Brand name items, like the iPhone, are not sold on Alibaba. If after sending out a request to buy the iPhone on Alibaba, you get email responses, (not from Alibaba) you are dealing with someone that got your email somehow and is trying to scam you. Anyone wanting to sell you a brand name item via an email stemming from a bid to buy something sent out on Alibaba is a scam artist. If they only accept Western Union, they are scam artists. No matter how good the information looks that they give you, it must be checked out via a third party. You cannot assume that Chinese people want to do honest business. The scammer's info will be incomplete, with something funny about it.
