A lady walked into game stop with a bag of a dozen snes games and GameStop was going to offer her under 20 bucks in the early 2005 or so. So I poached it for an even 20 on the spot by interrupting the offer as soon as they made it. It contained wild guns, Megaman x 2, Mario RPG, ff2, and some junk titles like Madden, Jedi, Mario world. So that was a pretty ruthless turnaround when I sold them at their peak in 2019 or whatever when everyone was over zealous about snes. Also I had picked up a copy of demons crest for 4 bucks at a flea market years before which sold for an absurd profit margin. They were loose but they were all in great shape and authentic. It came out to a couple grand all together
