I just bought a fish tank off some guy on Craigslist a week ago, since I don't have a Facebook account to use Marketplace. He told me it was in good condition, and the pics looked ok but were from kind of far back and it was full of crap. I drive 45 min to get it and the thing is horrendously scratched up on the inside because he used it for turtles and then storage.

Falling victim to the sunk cost fallacy, since I drove all that way, I took it off his hands for 25% less than we initially agreed.
