We don't know that anyone ended up with the wrong gauge shotgun. I always call and TALK to the seller. Maybe the eventual winner did too and got what he wanted. I have said I was going to do something at work and I didn't because I got caught in the shuffle and forgot. It isn't a crime.
Caveat emptor pretty much sums it up.
Brian it looks like you ran into one of the customers I was alluding to.
