I ALMOST had a really nice pickup today. I was at my local Game Exchange store and I saw a guy with a box of stuff he was trading in. Immediately I spotted some TurboGrafx-16 games. I asked if he had a console too, and it was already behind the counter being tested. He also had some boxed N64 & SNES games. I saw Donkey Kong Country 2, Super Mario Kart & Castlevania (not sure which one), and I overheard the employees telling him that the two Zelda's he had were worth around $50 each (I didn't see which ones they were).
He was looking for cash instead of store credit, and the offer was $66. He turned it down and packed up his stuff. I decided to wait outside for him and make him a cash offer. It looked like he had around $300 worth of stuff (the TG-16 games were pretty common releases, and I couldn't tell what condition the N64 & SNES games were in, or if they were complete). I would have paid as much as $200 for the whole lot. When I talked to him, he said that the store employees showed him an Ebay listing for a TG-16 console that was worth $799. I told him that the basic TG-16 he has is not worth anywhere near that much, and they must have been looking a a listing for a Turbo Duo, or a lot which included some rare games. Regardless, he was convinced he had struck gold, and said he wouldn't take less than $450. I wasn't going to argue or debate with him, so I said "good luck" and went on my way. I wanted to go back in the store and ask what they showed him online, but it was a moot point at that time.
By the way, this store sells games relatively cheap, which means their buyback prices are pretty low. I bought SNES Turtles in Time there recently for $15, and I once saw a TG-16 system for $45 (to this day I regret not buying it).
