I was out there earlier today to see if there was anything worth grabbing for the "two $20 games for $30," and saw that too, but I only wanted the T2/Total Recall set and they didn't have it. I just re-bought Requiem for a Dream for $4 (someone lost my copy of it a few years ago, paid me for it and I never picked it up again) and got the Robocop set.
Concerning the $30 deal, they have Viva Pinata for $20, but I wasn't sure if it was worth it and I couldn't find anything else anyway.
