Not a pawn shop, but was at a flea market a few summers ago - woman was selling next to new Craftsman and some nice Snap-On sets. I asked her the price, she said, "give me a number". I said "how's $50 sound", expecting her to laugh. Turns out it was ok with her. She also had some HUGE pipe wrenches and Channellock sets, most of which I snagged for an additional $50.
She told me her plumber husband had been having an affair. She kicked him out and dragged everything out of the garage to sell.
