I just got back from Mexico, and if your buying stuff in the tourist areas, sh*t is so overpriced! Viagra was $25USD/pill! Everything is on the shelves in plain view. I wasnt planning on bringing anything back, but I wasnt even checked going back through customs. 99% of the people werent that I noticed.. But going into Mexico, different story.. crap shoot! My girl and I got the green light. But the unlucky ones that got the red, had their suitcases looked through..
