I was at the Randolph AFB BX (San Antonio, TX) with my dad a few weeks ago--it seems they had an overstock of games marked down by about %25, even when there were unmarked games on the shelves. I saw some %25 off Capcom Fighting Evolutions (XBX), Splinter Cell:Chaos Theory (PS2) and even a Xenosaga II and MGS3! It's certainly YMMV, since the Ft. Sam Houston PX didn't have anything like this going on.
