Costco does sell wine and hard liquor here.No permit to purchase in MT for anything. Just do the background check or if you have a CCW you don't need to do a BGC.
I thought it was crazy to get a permit to purchase in MN, and have a CCW and still have to do a BGC.
Plus we have no beer restrictions in the supermarket, and can buy good wine there also. I wish the MT Legislature would ease up on the alcohol % so Costco could sell Port & hard liquor like they can do in WA state.
