I think Brownell's offers that discount too.
Had I gotten a C&R years ago I could have saved enough on transfer fees to buy at least another Mosin. But until a couple years ago, a fellow with a small shop close to where I lived offered amazingly low transfer fees. I'd buy some ammo there just to try to help keep him in business because it was so convenient and the transfers so cheap. Of course that was too good to last and he closed shop. Now I've found another FFL who offers ten dollar transfers, and I keep telling myself I don't need any more guns anyway (heresy, I know). I think that for anyone interested in surplus firearms, getting a C&R will nearly always look like the right choice, in retrospect.
