That �s a good idea! everybody should send him an e-mail so that he knows that he shouldn �t take anything from here. The text should be the following:

Maybe the Spansish speakers should help to improve it.
I guess that all the articles he sells here are fake. Besides, the phone number provided is of a cell phone so it �s difficult (but not impossible) to get more information through it. He doesn �t provide any information to make us believe that he is member of a serious company.
In this country many people are engaged in selling fake copies of "everything", music, films, digital books, PC programs, etc. But when they are caught, they are very severe with them.
