There are plenty of thrift stores in Tucson that support good causes but the Humane Society Thrift Store is definitely one of the best in town! They have a very nice selection of merchandise and their prices are fantastic. Naturally, they have a big selection of pet items (leashes, crates, collars) but they have housewares, artwork, clothes, and furniture, too. It is well worth a look! It's on Speedway near Beverly - near the Live Theatre Workshop & Something Sweet Cafe.
