Be jealous.
F-Zero GX - $5.99 from used game store (3rd copy, 2nd "complete". just in case someone manages to ever enable LAN play...)
Tetris Axis - $5 from Kmart. It was open, but everything is in there. For a prize, that's fine.
Nintendogs - $4 from Goodwill - I now own every version of Nintendogs and Nintendogs + Cats.
Three copies of CrossworDS Plus - $4 each from Goodwill. New and unopened. One for me, two for prizes in my StreetPass group.
GBA SP/original DS AC Adapter - $1 from Goodwill. If you're checking Goodwill stores, they usually have a tote of random cables somewhere. Might find something useful in there.
Final Fantasy Adventure (Original GB) - $2 from Goodwill. With plastic case.
10 packs of 5 packs of 5 NSMBWii stickers. $1.50 each. I have this entire set, minus one. These didn't get an official release in the states, but these were in a "liquidation" type packaging. Hopefully, between the 250 stickers, I'll get the one I need. Extras will make for good, cheap prizes.

Now, the bottom half of the screen.
The Orange and two Black official GCN controllers - good, clicky sticks, nice condition (needs a little cleaning). $3 each from Goodwill.
The Black GameCube, the off-brand Indigo controller, the MC251, the random WaveBird receiver, power cable, A/V cable and Nintendo-specific off-brand RF Modulator - $25. The Gamecube is pretty close to a launch unit, looks like it was purchased in June of 2002 at... Kay Bee toys. Funny, eh?
Pretty soon, I'm going to build a fort out of GameCubes. I will call it Fort GameCube. Yeah, I came up with that name all on my own.
