Air freight is not cheap. I try to bring back on the plane as much as possible as the baggage allowance of up to 140 bs or more can equal about USD800 in air freight costs.
EMS. postal is least expensive. More difficult to track and not as quick as UPS, FEDEX , or DHL.
Definately don't ship any fake products as US customs is on a high alert for fakes and will confiscate all the items in your package if they find any fake stuff. According to Customs regulations you are legally allowed to bring into the country 1 fake item of differing type..ie: 1 watch, 1 bag, 1 wallet, but don't think this applies to shipping..only transporting through port of entry.
