I'll start, since it's now officially the weekend.
At work:
Halo 2 Limited Edition - $50 (employee discount)
Gran Turismo 4 display card - free (finders keepers)
At Goodwill:
(SNES) Yoshi's Island - $4 loose
(SegDC) Dave Mirra BMX - $4 complete
Not much, but Yoshi's Island made my day. And Halo 2 is pretty damn good!
