It really depends on your area. As you have learned Goodwill is not a bargain and don't get me started on their other issues. Usually the smaller the thrift store, the better deal you could get. I work at a dog rescue shop, Luv-To-Save Thrift Shop for Boxer Luv Rescue in Phoenix. After so many days, we discount items as low as $1. Everything at our store is donated and everyone is a volunteer so all the money (minus expenses, rent, electricity) goes to the dogs.
