I know it does, well, at least where I live in the south of Mexico City but what services are available for general mail such as small packages that's secure but inexpensive (international)? I'm considering starting a small mail order business for some extra cash. My post office is small & the staff doesn't seem very experienced with international mail so just refer me to expensive couriers. I had a colleague a while ago who had a similar business & was using a good mail service but I lost contact with him so can't ask. Ideas anyone? Thanks Carol
