I send stuff through Asian Express to Norway- It arrives within 3 days on our doorstep and tracking code is of DHL.
The rate per kg is 750-/ and I am sure it must be cheaper for America. DHL charges 1320-/ kg lol.
The only difference between them is that Asian Express is an agent of DHL, hence you get tracking number after 1 day. DHL gives it on the spot and you gotta pay extra.
