Community Thrift Store is one of the larger thrift stores in the Tulsa area. They have a nice selection of clothes and household items, and once in a while they receive some nice household furniture, you just have to be there at the right time, because it does go fast!
They offer sales on certain days, but honestly, their prices are low enough already. Many of the thrift stores in the Tulsa area are kind of crazy with their prices, charging almost as much as you would pay retail! But at Community Thrift Store, you really can stock up on play clothes, etc. for a wonderful price!
