Doesn't' matter if they re-code them. If you buy a burger at the restaurant in the store that sells predominantly firearms, the sale will be recorded with the new code. I believe SOTUS said firearms and ammo are protected. I'd love to be on the side suing the big business for infringement. However, they will not be tracking induvidual sales, only that you went there. I'd buy everyone there lunch just to sit in on that lawsuit.
