Parts Prices, WTF?!

So many times I have taken the time to box up parts, and get shipping quotes, then the prospective buyers flake out on me and disappear. I have 2 boxes in my trunk right now for that reason. Will unload and put them back on my sales parts shelf. Running around like that costs money and time too. When I no longer need parts for projects, I'm gonna do a mega unload of it all and be done with it.
