I bought the cans of ammo from this guy Friday. He was trying to sell this gun ASAP because he bought a gun on GunBroker and he needed to pay for it in 10 days or he would lose it. Seemed like a good guy just trying to scrape up the money for his purchase. Maybe he was a little too eager and sold the gun out from under you but if you were in the same pinch for money would you hold on to a possible deal or go with a sure deal?
I would not have reneged on a deal already struck. Given my fondness of buying/selling/trading, I've had MANY occasions where I could have, and can honestly say I never did. It doesn't matter if someone shows up ready to pay you sooner/more. Have a little class and let your word mean something.
I know I'm asking a lot from people nowadays, though.
