I discovered a Thrift Store Directory. You can enter either the zip code or name of the city and it will list charity driven thrift stores, ratings and reviews.
Thrift stores are great places to find items for less than retail stores. Many things can be found with original price tags and boxes. One thing about it is that you are not guaranteed to find what you are looking for. Part of the fun of thrift shopping is the treasure hunt or unplanned purchase of something you have been looking for, for a lower price.
I have found many things for a fraction of the regular price that either were brand new or looked brand new.
