$3.50 a piece for new releases is impossible. They are either counterfeit or what they are claiming to be new releases are in fact 2/3 years old. It is not possible to get a new release for that price. A website claiming to sell new releases for $3.50 should send alarm bells ringing straight away.
There are plenty of wholesalers in the US for DVDs but you would be looking more like $12/15 a piece for a new release not the $3.50 a piece that site is quoting.
Run a search on the forums for DVD wholesalers, there is some gold to be had..
