The GameStop Throwback Flash Sale is running Thursday and Friday. As part of the promotion, you can get five pre-owned games for $10.
This is the second pre-owned game sale this week at GameStop. In fact, the Buy Two Get Two Free Sale is still running.
Some of the games are the same in the two sales, but not all of them. The Throwback Flash Sale tends to be older games. The B2G2 Sale tends to be newer and more expensive games.
