Hi! I posted this on the other board, but now think this may be better place to get my question answered. My husband wanted to send a letter with a couple of pictures from the US to Cancun, and was wondering the best way to do it? It doesn't have to get there really fast or anything, but when we checked into UPS it was about $34. and that seems like a lot. Does anyone know if you send it thru the US post office Airmail if that is a good way? Any help would be appreciated. Thanks!
