In that Grandpa response to The Ginsue, he said, "I've been here 112 years, sold 25000 guns, have a good business, plan on being here a long time without Buds, Who's going to do your transfers when there are no retailers????"

112 years is one hell of a long time. It still sounds to me like collecting a fee of $35.00 is damn easy money for processing a FFL transfer. The firm doing the transfer has no money tied up in the firearm, and making that phone call for the background check sure can't cost much or really take that much phone time.
Now, I know that when saying the following that I am like comparing "apples to oranges" but here we have at least ONE good thing for the gun show consumers that State of Colorado has established and that is that FFL dealers at gunshows may NOT charge more than ten bucks ($10) for handling a transfer at gun shows.
Even though I too am a old Grandpa, I'm sure as hell not that type of Grandpa that would go back on my word, especially printed word.
I will "bust my ass" to stick with my word when I give it, kinda like the old fashion handshake bond.
