*In general, air mail takes about 2 weeks to get to and from Peru, so send stuff early! Packages can take even longer (4-6 weeks). If sending a package, do not make it too large or it might get stuck in customs for a while and I might get charged large fees to recover it. Furthermore, cover anything mailed to me with lots of religious paraphernalia (crosses, Bible verses in Spanish, etc.) as for some reason this seems to deter people messing with the mail.
