Freecycle.org puts together "one man's trash and another man's treasure." There are literally hundreds of Freecycle groups all over the world; just find one near you and you can post that you need something or want to give something away. There is a HUGE variety of stuff that is available, and since it is free, not all of it is, shall we say, mint in the box. But you'd be surprised at how much cool stuff you can find.
