I'm not a big fan but I still stop in a PnT at least once every couple weeks (there's 2 near me) and once in a while I'll be surprised at what they have. Last time I was there I saw a Saturn system with hook-up's and controller for $19.99 which was pretty good. They also had a Suikoden II for $70 which wasn't a bad price either.
Pretty much all of their current and last gen games are priced exactly the same as Gamestop or higher though. They did price match a used copy of Burnout Paradise for me however (was $23.99 and I got it for $17.99)
