Purely anecdotal, and focusing more on the website than the science...
A few months ago, one of my kids was on Facebook and knew I was looking for a gaming computer for my youngest. She saw an ad, clicked on it, found a site with several models of high end gaming laptops, and in an effort to surprise her brother (and lighten my load) she ordered one for $179. Keep in mind, this is normally a $1,600 laptop, but was being sold as "refurbished - like new/mint condition."
When the T-shirt arrived from China 3 weeks later, it didn't even fit her.
A lot of Chinese companies are selling cheap items (clothing, fake jewelry, etc) via fake fronts. So you order a Laser Rust Removal System, they send you a tracking number a few days later, then packages "get delayed" and when it finally arrives, it's an item that the company ACTUALLY sells, but you've missed your window on a chargeback and now have a $180 V Neck T-Shirt.
