Trade as far as what? Are you looking to bring some items to sell and make some extra cash or barter? Most items in Bogota, from my experience, that are in demand is technology and name brand clothing. I have friends in the states which will buy a Tommy Hilfiger shirt on Clarence for $20 and sell it in Bogota for about $50. New black berry and iphone Cell phones are usually on the pricy side. Also new video games as well.
