Good try man! Thats a scam guys!
And you you have any serious evidence to back up your claim? We need to be very cautious of calling new service either a scam or totally trustworthy project.I wounn't call 3% fee - a totally insignificant money. And in my opinion it should be more of a fixed fee, especially for low transaction.
Noone buys anything without a preview! He just wants people to fool each other and receive some fee by process. Any trusted numbered member may fool others too. No guarantee on his project
How you are able to buy something from satoshibox and you can't do it from here ?
A trusted members on bitcointalk, he sell you something, if the product received bad you can rate it !
If you want a service that have escrow, you have to use pastecoin.com or other services like this.
