Snowman357,
Well, I am getting ready to renew my C&R for the third time (3 year license). I must add something not mentioned yet that the C&R allows you to do. One of the main reasons I have one, and use it for, is to be able to go to gun shows, or even on vacations, and at flea markets, local estate auctions, as it enables you to legally purchase C&R firearms wherever you and legally take them right into your possession. This is across state lines,etc..waiving any "waiting period" as some states have.
I have used mine for direct purchasing from wholesalers, like AIM, SOG, Century, etc.. but the methods mentioned above have been excersized much more often.
Just my .02 worth..
