Are These Xbox 360 Games Cheap?

i bought today gta episodes from liberty city the comple edition and assassin creed 2 and need for speed hot pursuit ,all for just 10$, yes ten dollars, but of course not the original , the copy for a modded xbox 360
Thanks

Assassin's Creed II is by far one of the ebst games i have ever played. The graphics are outstanding,and the gameplay is even better. Its great because the missions are fun, and the open world aspect akes it even better. I would recomend this game to ANYONE with 20 bucks on them.
