I don't, since in New Zealand, pre-owned games are about five bucks (If that. Sometimes they even cost more, ffs) less than new ones. The only time I buy pre-owned games is when I can't find a new copy.
Although a couple of months ago, I bought a pre-owned copy of Hitman: Blood Money. Inside, the case had a crack that split into three cracks further on. The inside of the case also had a cock drawn on in permanent marker. The manual was also worn on one specific corner. "Holy shit! This is the exact same copy I traded in five fucking years ago! BLACK MAGIC ABOUND!"
