Congratulations on the great finds!
How much do you save when you factor in the amount of time pawing through junk? My first wife (now deceased) was a garage sale addict, so then that time was a "sunk cost." Yes, I got some great deals on stuff. But, I had to spend a lot of time looking at junk while she searched for treasure.
My present wife is not a garage sale fan so I pay more, but have the time for other things.
