I aways deal with USPS for international shipping, their rates are amazing. Shipping time ranges from deathly fast(canada, 3 days), to excruciatingly slow 1.5 weeks to eastern Europe.
But UPS and Fed Ex stick it with really high fee's. Most people seem to prefer USPS when I internationally ship.
Guys, I started a thread about 6 months back asking amp manufacturers why their shipping rates were so high, and I got a couple of replies from Justin at Headamp - basically, his customers want their amps as quickly as possible and that means one of the US carriers that charge an arm and a leg. I certainly dont blame Justin for that, but its interesting that EMS can have iBasso gear to me within a week from Shenzhen while it takes longer than that to have Australia Post ship something from Headphonic in Perth. Same country, no Customs, but it sits in the Perth Mail Centre for days on end - there is a lot to be said for finding an efficient courier service.
