For consoles, quite a few. I picked up a NES in a box in awesome condition (guy was a trucker, said he barely played it and had no kids), the Zapper, an Advantage, and around 10 games for $3. Picked up a spare NES for $1 at another with no cords, but it was jammed in the box for the top loader which I figure is worth more than $1 to someone. Gameboy Color for $3 with the rubber drop pad, another GBC and a GBP missing battery cases for $1 each. GBA for $10, GBA SP for $15 (with charger and everything)
But my personal top is my Mountain Dew Limited Edition XBox I got for $20. Came with an s-controller that looks like the Halo Limited Edition one (it's that dark see through green), a few sports games, Flatout and in the disc player, a copy of COD: Finest Hour.
I also got a 360 from club.live, but it died after two or three years of use.
As for games, I once hit a yard sale and bought Final Fantasy, Power Pad, and World Class Track Meet for the NES, and for the Genesis Shadowrun, Phantasy Star 2-4, Shining Force, Battletoads Double Dragon and something else for $6 total so it came out to 60 cents a game. At another, I bought a ton of Zelda/Mario games for the GC for $1 each, and unloaded them to amazon for a nice profit as well as picking up Zombies Ate My Neighbors, Super Mario Kart and I think another SNES game or two for $1 each as well. Also, Marvel vs. Capcom 2 for the XBox and MvC for the DC. Dumped MvC2, ended up buying another copy of 2 for the PS2 that was 3 for $1 at another yardsale that's missing the case (along with a just disc of THUG2 and GTA2 Greatest Hits in the case)
Oh, and Overlord for the PS3 at K-Mart for $1 (and I used rewards credit from stuff my mom bought). Ended up sitting on it for a while out of laziness and then dumped it to Best Buy for $6 during a 100% trade in bonus sale.
Oh, and Dead Rising for the 360 for free from glyde and one of the Fire Pro games for GBA for free when goozex launched. Both thanks to this site.
