Sorry, this is only remotely related to traveling, but I don't really know where else to ask.
My wife and I were married in Costa Rica (Punta Uva) last year and we were interested in ordering/importing several bottles (~3) of Cacique Guaro for sentimental reasons. We live in the US.
I would obviously pay for the bottles, the shipping, and a reasonable fee for your time. From what I've found out, the only customs issues with that small of a number of bottles would be a fee I would pay upon receipt, so it's nothing you'd have to worry about.
If you can help out in any way, I would certainly appreciate it.
