Marvel Ultimate Alliance & Forza 2 (360) together for $12 w/ free SS shipping. Both games are well worth that price alone and had no clue they were being sold together: (EDIT: Doesn't seem to be working now.)
Scribblenauts (DS) for $11.32 new w/ free SS shipping:
Shadowrun (360) is also criminally cheap for how fun it is, for under $10 shipped from various sellers:
