Here is a doozy! I found this awesome Brown & Sharp caliper tool near the bottom of a random hand tools bin the other day! The digital readout wasn't working so I laughed and said I would offer them $5 for this broken ol' caliper. "If it workes with a new battery - it worked and if it doesn't I'll toss it in the trash." I said. The guy behind the counter looked at it and said, "sure that's fine." Little did he know these things are some big bucks! Used on Ebay in kinda rough condition they are worth over $100.
And yes the digital readout worked once I threw in a new battery.
