Not much longer than yours. Mine ends October 12th. :( $30 to get 20% off on new games for 2 years pretty much paid for itself after the first few purchases. It really was a great deal.
Yeah, no kidding - I'm so sad to know it's going away, and there's nothing I can do to stop it...
...that said - I just don't see how on earth a program like this, was not going to bankrupt BestBuy at some point! 20% is a pretty huge discount - especially since it's on ALL new games (whether released now or two years ago!). Even Amazon Prime wasn't that aggressive with their 20% discount - it typically only applied to specific new releases, and only for the first few weeks after release.
