I bought Suikoden II for $15 I think. I played it for 20 minutes, didn't like it and gave it away to someone for free. Can't imagine why people like it so much.

Back in the early 90's when games on CDs were relatively new I got a couple CDs with 5-10 PC RPGs each on them. One had Populous on it and another had Populous 2, which are really great games. One had Might & Magic III, another great game. I got a King's Quest that way too, can't remember which one. You never know what you'll find in a bin of crap no one else will buy.
