well DHL and fedex are way more expensive comparing with General Post. Once i had to send 4KG parcel from Doha to Norway. I checked with DHL and they estimate the cost around QR1300 and would take 2days. I checked with GeneralPost they estimate around QR280 with 4days deliverytime. I chose General Post and it took 6days(+weekends) but goods arrived there safely. Now its upto you how urgent you want to send.

hope that gives an idea.
