Air cargo is the safest, though not as convenient. Of the times I've had door to door delivery, from; FedEx,UPS,DHL and USPS all the packages looked as if they were handled very roughly and about 80% of those I had leaking bags and about 50% of those the fish were D.O.A.---These packages move through multipal facilities at fast dead-line pace and the packages are handle very rough ( I use to work at UPS in Chelmsford, MA and seen it first hand,,,hell--handled packages roughly first hand).
real bummer StIcKy, next time try Air cargo, Manchester,NH has a pick-up
