Rochester has a wide variety of thrift stores, many run by non-profits such as the Salvation Army stores, the Goodwill stores, the ABVI stores and the Am Vet.
The selection can be varied, but if you're looking for a cheap furniture, $1.00 vase, a $2.00 inkjet, unusual books or $4.00 jeans that are barely worn, it's hard to beat a thrift store.
