I just looked, and you can go to the NRA website and there's an online store where they sell all kinds of swag... but I think the better question is why aren't you supporting the Canadian gun orgs since the NRA doesn't operate up here? The NFA and CSSA would probably be a better choice for sending your money to.
Don't Join the NRA instead of the Canadian firearms organizations, Join the NRA in addition to them.
My America's First Freedom subscription is invaluable; anyone who has read one would agree. The United States is one of the last places on earth where firearms rights are the norm. The USA is the last bastion, and they're actually making some progress in firearms rights. The NRA's work in the United States helps us all.
An NRA membership comes with your choice of NRA magazine subscription - such as American Rifleman, American Hunter, or America's First Freedom, depending upon your primary interests - and two stickers which serve to make public your membership in the NRA, and your moral and financial support of it.
