I'm not sure it would be worth the hassle to set up a specialist shop of this sort to rip people off
There was one that was around for years. Thankfully seems to have gone now. This is the last reference I could find about them
The interesting thing was it was the low low prices that were the attraction and people kept on sending money for years after the warnings were being posted. I suppose it is just human nature, after all people still fall for the 'give me your bank account details so I can put 100's of millions of dollars into your account' scams.
Still a couple of businesses out there that I would not touch with a 14 foot battle lance (homage to, Bored of the Rings).
I can understand a new business starting up with ultra low prices to get things going. So perhaps thats the reason for it?
