The one in Mansfield is pretty hit-or-miss. I'm a bit biased against them since they wouldn't give me a job and the guy only hired hot girls, but I did pick up Infinite Undiscovery for $14.99, and they're the only place in town for old games. They also had Elite Beat Agents for $2.99, and I was going to buy it but my friend called me gay so I put it back.
I bought a Turok that didn't work, and I returned it and saw it back in the case the next time I was in there. But most DVD is $3.99, so that's pretty tough to beat. They have a lot of stuff that I would buy if I had mad amounts of money strictly for collection purposes.
