Here's what I have either picked up or can remember seeing. There are a lot more (probably 70% of all XBox games) and a handful of PSP titles (all sports from what I remember).
XBox (all $9.99 unless noted)
Apex
Arx Fatalis ($19.99)
Atari Anthology

Bionicle: The Game...
FYE marked down a lot of XBox, PS2 & Gamecube games to $9.99 in early April. You will rarely find the correct prices on the games, but there are scanners throughout every store I've been in (though I didn't notice them until yesterday) that you can check most titles at. Some will scan as item...

Basically, the 2 for $20 is on all games $19.99 & under except XBox & XBox 360. The only thing you have to make sure of is you have an even multiple of...
It's not that mysterious a vendor. All of the frontlane product comes from one of two souces, SVG in California (parent company of Crave) and Jack of All Games in Ohio (owned by Take2), which is why there are so many Crave & GlobalStar (a Take2 imprint) titles in the mix. SVG has been stocking...
The .98 prices are clearance, the .95 prices are not. Basically, it's a universal drop to $20 and TRU is taking it off clearance so it will be restocked.
