This kind of post is pretty useless. If you are unwilling to name the retailer then why bother to post? If you are unable to name the vendor due to the constraints of this forum, then I still dont see how this is constructive.
There are always ways to protect yourself, if you failed to use the means available to you then I dont see the problem.
If you chose to violate the law then you also chose to accept the consequences of that action.
If I am mistaken in my assumptions then I apologize, but your vagueness only leads to speculation.
