Ordered an Ebook (Sue Grafton's Y) and never got it. Only a couple dollars. I suspect they bank that you will buy a cheap book or music/game and it's such a small amount that you will not refute it.
Some things to note:
They a slow or will not respond to email, their phone number is no good. When they do respond, IF they do respond, they are very very poor English speaking and sound like a 3rd grader. The Physical address is a small two bedroom house in Michicgan, unable to house what the site has.
It is my opinion, that these people are rip off artists, immigrants ripping off people. Even if they are not ripping YOU off, there is no way for them to have Ebooks that cheap. They would have to have a liscense for it....
WARNING: DO NOT buy from these people. In fact, Do what you can to shut them down.
