When we were still visiting Mexico on a yearly schedule, I happend across a "loophole" concerning amount of liquor (specifically tequila) allowed back into the US. I had 2 shopping bags of the Miniatures such as on airplanes, due to the constant request from friends/family to bring me back a bottle of Tequila....3 different times, I admitted to the US Officials of what I had and they never flinched at saying "go on " Don't know for sure if its because they thought it novel or if there is no required amount allowed. Of course, one can always offer to pay the required duty if you have more than your allotment.
