I'd have to say Circuit City, for letting me PM a penny guide with a receipt from Best Buy from about 20 minutes earlier. LMAO
Personally, I'd probably vote for Kmart if it were on the list, since I still find some great deals there, but not so much at the other ones. Though, I will say that my $1.99 Beatmania bundles from the 2007 game clearance @ BB would also qualify them for a vote.
But, I'm gonna have to stick with my original vote, Circuit City for the penny guide PM. LOL
