We're shortly (Covid permitting!) going to be going to the US and we want to take several bottles of spirits with us as presents - things the family like that you can't get out there. The allowance per person is one litre, and we want to take more than this. I think this means we go through the red channel in customs and pay excess duty on it, which as far as I can see is a couple of dollars. Has anyone done this? Is it straightforward or something that will be a huge pain at customs?
