I don't have a link to the ad itself, but there was an ad that got reposted 4 times on my local craigslist that was as follows:
Title: Rare games
Dungeons and Dragons: Heroes - Xbox, $60
Baldur's Gate: Dark Alliance - Xbox, $60
Gauntlet: Dark Legacy - Xbox, $60
Mario Party 8 - GC, $40
Bard's Tale (new and sealed) - PS2, $20
Then he had some really snarky paragraph about how he wouldn't even respond to "lowballs." All of these games were used (except for the last one), and they're not worth nearly as much as he wanted. The last three times he posted the ad, someone made a response ad (one time was me, I dunno who the others were) calling him on his bullshit. Made me feel a little better when I saw that I wasn't the only one who noticed how much of an ass this guy was being.
