As part of the bankruptcy, Radio Shack (or specifically, the company that bought Radio Shack) is selling off all their customer data to interested 3rd parties. http://www.slate.com/blogs/mon.....t_people_s_data.html

Remember having a conversation like this with the cashier?

Cashier: "Can I have your address?"
You: "No, why do you need that?"
Cashier: "Oh it's just for our records.  We won't give it out."

Yeah.  Right.
