To ship don't go to any Cargo Comp[any because they will charge you more then what you will pay if you use Qatar Airways. they use Qatar Airways as well but they charge you with the services fees. you can save the difference that you will have to pay it to them by going directly to Qatar Airways Cargo Office and Ship what ever you want.

Qatar Airways Cargo is located in the Main Airport Street that lead from Toyota Signla to Al Wakra. The Office is the opposite side of Family Food Center in Tthe Old Airport Area.

If you are coming from Al Wakra to Toyota Signal, and after Old Parashute Round About, you will find a traffic signal; pass it go straight, and after few meters you will find a gate in your right side, and you will see a big board of Qatar Airways. that's where you can ship what ever you want.

Good Luck
