Yeah, I like it when that's possible - I go get a small haul from somewhere and they throw in some freebie or there's some small item that's worth something, and makes up for the other costs, so it's pretty much free.
I paid $5 for a Power Mac 7200, display, keyboard, and mouse from a garage sale. I sold one of the PCI cards out of it (GPIB) for $200 on eBay. Best haul ever in terms of that.
