First and foremost, i know i spelled by wrong, shut up, i'm not retarded. This is just a heads up for people that tend to get gamecards from best by, and paying nothing for them, also known to some as theft. I have a friend that works as a manager at best by, that's how i got this information.
Recently, blizzard has influenced best by to recall all their game cards and games so that they can implement a tactic that each gamecard and game, has to be SCANNED FOR PURCHASE before it comes active. Hense, you take one, without paying, it doesn't work. I don't know if this is in effect yet, but i know it will be soon.
I also have a friend at game stop, no word on this happening there, but their cards are held behind the counter or in the back -.-
Anyways, hope this helps the select few that steal their game time :]
