A local woman had a good idea... buy wholesale and sell retail on ebay. Except she "bought" wholesale from Chinese companies online who ripped her off. She sent a Money gram... they sent empty boxes. No iPhones, no Playstations. The BBB says use a credit card - if the company doesn't want to go that route, that should be a big red flag.
At least with a credit card you have some recourse. That woman is now $1,700.00 poorer, but wiser.
Here are the sites. The BBB says these are the scammers.
