Jesse, it depends on what you are buying. I have two pills that I take every day, and they are slightly cheaper in Chetumal. I have never been charged import duty on them, but I'm also not bringing in commercial quantities. These same prescriptions would be much more expensive in the U.S. as I have no insurance PLUS I would have to get a prescription from a doctor, and that would add to the cost of the medication in the U.S.
