Good luck while it is in transit within Mexico... you know it can be lost, but I with you the best
by the way, it went through the aduana, but it doesn't say if you will be charged taxes for it, but since it was sent through USPS, it may not get inspected but the downside is that it probably will go through SEPOMEX....
I firmly believe that Mexico is not a 3rd-world country i many things, but in postal service it is .... is there a 4th-world category for postal service?
