The Book Barn on 32nd and Main in Joplin has a wide variety of items, mostly used some new. Everything from books to music to collectable toys to trading cards can be found there.
Prices are reasonable if you can find what you need. I only gave a good rating because, for a few dollars more, you can be assured that the cd will play and not have to take back one that doesn't. I don't like the idea of them buying anyones used cd's as I think it contributes to local thefts, but that's just me.
