Why doesn't someone create a reverse eBay of sorts? I'm looking for a way to… “backup” my Game Boy cartridges via USB. I found a few scattered online retailers that carry the Gameboy Advance XG-Flash 256MB, but each one of the sites has lousier than lousy ratings. Even Craig's list didn't help me (and where's their RSS feed?!). Perhaps I should offer them some of my blog stock?
