Just a quick tip, if you're going to Serpost (the Peruvian post office) do not tape or seal your packages before going to the counter. They'll have to check inside the package to make sure you're not sending anything illegal or drugs. Trust is still an issue in Peru. Even with x-rays and such they still require the post office workers to double check all packages.Keep in mind that learning Spanish will greatly help you out when you're trying to figure out what they're saying at the post office. Knowing Spanish will help you assimilate to the culture and you'll be able to communicate easier. If you're looking to learn Spanish, check out Synergy Spanish, Rosetta Stone, and Fluent in 3 Months.
