It's $10.04 for every carton over the 1 you are allowed.
If you bring 2, we're likely not going through the paperwork of charging you $10.04. At my port, you can bring in a few extras and we're not motivated enough to charge you.
Now if you're one of those guys that brings in a whole suitcase, you're gonna have a bad time. I think the most I saw was 144 cartons. At that point we get into it being commercial merchandise and all the problems that come with that.
