One that stings the most was a pristine 32 inch barreled, Fox A grade in 20 gauge for $1,000.
I can remember thinking 32 inches was too long for a SXS. What the heck was I thinking?
It was long time ago but it was still bargain, went back the next day and it was on the shelf behind the register with a deposit ticket on it. Seeing it again made it even harder to walk away the second time.
