I've had a C&R license for some time and what I like about it is, besides having guns shipped directly to your door, is that places like Midwayusa.com give some decent dealer discounts one you send them your license.
Iwas considering it for a while but I decided that I don't buy enough to warrant the hassle of it all I'll buy a gun at the gun show or shop maybe one in a great while, so I really can't benifit from it, same goes for shoping at midway too once I got all my reloading tools I stopped making major purchases.
I personally didn't think it was much of a hassle; $30.00 for 3 years, fill out some paperwork and send it off; I got the license in about two months. I have saved the $30 many times over in transfer fees and discounts. Actually I will tell you the good thing that it made me do was make me more diligent on keeping track of my guns in a binder; even the non C&R ones so that was a good thing for me.
It's always a good idea to have your guns's serial numbers written down somewhere, just in case the worst happens. While I have a safe, it's not fire rated so if the worst happens at least I can get some more money from the insurance. Everyone should do themselves a favor and keep a copy somewhere other than your own home.
I've had mine for quite a while now but may not renew. I've lost most interest in the C&R pieces and midway's discount has shrunk to the point where I can order from other places without a discount and still come out ahead once you figure in shipping.
