Looks like the awesome and somewhat difficult to find shooter, Ikaruga, is now $19.99 used at Gamestop:

Not available online, of course, but if you've had this on your want list and have it at a local store, it's no longer $44.99/$39.99/$27.99...quite a bit more palatable at $19.99 + 10% off w/ EDGE = $17.99
And of course, while you're looking for other Gamecube rarities, the two Phantasy Star Onlines that are worth something, PSO 1+2 and PSO 1+2 PLUS, are $4.99 each, as they have been for years now (good luck finding a copy of either):

And don't forget NCAA 2K3, also $4.99 (again, good luck finding it!):
