When stuff has to go

The unfortunate side of our pasttime is that eventually we run out of room, and something has to go. Its a no brainer for commodity items like generic monitors, easy come, easy go, and often profitable. Same for the really odd bits, you keep them forever if they seem the least bit interesting, well maybe not. What about the rest, the stuff you take to a swapmeet and nobody looks twice at. Case in point, I was dumpster diving the other day, and pulled out some IBM 3812 laserprinter toner refills, a HP Scanjet isa I/F card, and some weird tungsten HP plotter bits and pens. It just didn't seem right to leave this stuff behind as I harvested a few choice shipping boxes, but eventually I will have to question my judgement. I am wondering about creating a list of last resort, with the catchy title of 99 cents and shipping, where every item listed would be 99 cents and actual shipping costs (ie token payment, but it gets a home).
