Opportunity Cost

If you've ever bought something for a specific use and employed it successfully for that use, then stored it and kept it and moved it and eyed it and moved it again, workshop to basement to barn to storage to yard...think about it.

That item probably owes you nothing at this point, and paying it homage by paying to move it across country is a fool's errand. That thing has done its job and needs to cycle its way along the path. Craigslist or Freecycle come to mind as great avenues of disposal.

The recycle dumpsters and 1-800-GOT-JUNK come next.

Don't try to realize any money at all...don't expend your time and effort but throw your remaining resources into getting the things into someone else's hands.
