Mine are mostly B2G2 around here. Back at home there was a slew of B2G4 locations but...well, I cleaned them out of most things, admittedly.
Seriously, B2G4 + 10% Off Used + Edge Card = ~Ridiculous~
Of course, they shouldn't have taken the 10% Off coupon but I'm not complaining. The only problem is that most of those stores are just emptying out what they have left, so that's pretty much it on that front. No more deal-mongering there. Sadly, the B2G2 places around here are pretty much in the same dire straits.
Great fun while it lasts, though. Go over and give it all a look. You can get some stupid deals through this if they have what you want. I highly suggest HBO boxsets if they have them, mostly because some of those have ridiculously low prices to start as opposed to...retail.
