I was in Press Play in Barton Creek Mall yesterday and they were basically liquidating the place for their 4th or 5th move in a year.
50% off most disc games
70% off most cart games (30% off if they have the original box)
Of course, rarer titles have little to no discount at all.
I picked up Alisia Dragoon, Rolling Thunder 2 and Strider for $6.60, loose.
