Local mom and pop game stores are pain in the asses here. As noted above, the most sought after games cost a bit of cash there. When i needed an SNES fix, last month I had to drive around to find a SNES at a conceiveable price. I found several game stores offering them above 60 bucks. And several of those game stores also offering their games for more than 30 bucks. Normally I wouldn't care really, but it just drove me nuts when I saw a price list of games they wanted to buy from customers. One store would buy Tengen Tetris for 3 dollars, and they had a few for sale that were marked at 75 bucks.
Also, does it seem that the classic series on GBA is going down in price everywhere, or is it just me? I wonder if it's the fact that most no one would buy a single NES game for 20 bucks.
