I get decent scores at thrift stores. Recent purchases have been various gym clothes for max of $4/piece, penguin originals shoes for $4, a working Sega Genesis and 7 carts including two controllers and the cables ("Sonic and knuckles," "micro machines" and vectorman 2) for $30, a 40 watt X4 Lloyd's am/fm/dual-cassette receiver for $10, and a pair of sbl70's for $12. I plan to sell the audio equipment when I can bring myself to do it. I have a buyer.
A friend grabbed an RCA turntable/am/fm receiver with matching speakers for $10.
