Re: What is your best " free box " or OH! you can have that find?
I can't remember much either, but a few low dollar scores come to mind:
I was at an auction, and a guy pulled 3 albums out of 5 boxes of records, and then gave me the 5 boxes. I sold the albums for $1-$2 each, and probably cleared $350 on the deal.
I just scored a super nice commercial Rubbermaid mop bucket and ringer out of a commercial clean out...I have it priced at $35, plus $3 each for the mops. About a $50 score all total.
I did score a large box of plumbing parts and fittings...probably about 40 pounds of new #1 copper. I still have it, but it should easily be $100+ box.
