T.H.
The two Philadelphia thrift stores I go to most often are Circle Thrift on Frankford Ave. in Fishtown (proceeds benefit Mennonite Central Committee [MCC], which does overseas missions) and Super Thrift on Aramingo at the Thriftway Shopping Center.
For special, I drive to Care N Share in Souderton, about 30 miles away. They have EVERYTHING--kids' clothes, kids' toys, household goods (we got a fabulous dining room set and living room rug), you name it, in three stores. Proceeds benefit MCC.
Good luck,
Jean
