I don't think John ever mentioned walk-ins Bill.
My understanding is he's disappointed in eternal tire kickers wasting everyone's time. Over the transom.
I gotta say, and I don't care if people get mad or not, but a $300.00 trade-in shotgun isn't worth my whole afternoon. And I'm not even in the gun business.
Be respectful of the peddlers time.
FWIW, it's been my experience that the person haggling until there's blood on the floor isn't going to buy again anyway. Some sales aren't worth the grief.
I can think of at least two internet personalities that have spent 10's of thousands on shotguns, and still have absolutely no confidence in their ability to vet a firearm. I don't even know them, and I'm already tired of them as soon as they start a thread somewhere. They probably call John~!
Though I'm pretty sure they'd only would get dial tone at Woodcock Hill!
