Fortunately I have never been involved with a seller who would not ship a C&R gun to my C&R address. My local 01FFL "only" charges $30 for a transfer. However, I would have to decide whether a gun that I really wanted was worth $30 more if I ran into one of these ignorant and/or greedy sellers who refused to honor my 03FFL. Why did the BATF create the 03FFL if not for this? Its like the local drivers who won't turn right on red when the intersection is clear, even though they legally can. Even if you have an H1 with an I-beam welded to the front you can't legally push them through the intersection, even though thats what you would like to do. Like Ron White said "you can fix ugly, but you can't fix stupid". Unfortunately, there are a lot of unfixable people out there and gun collectors and dealers are not exempt.
On the other hand in the rare instance where I sell a gun and the buyer demands that I ship it from an 01FFL, he is going to pay the $30 or he doesn't get the gun.
