SaudiMac has a price list of the new MacBook Pro models. But should you buy them from Saudi Arabia or just buy them online from Amazon.
Quick overview on your Apple choices in Saudi Arabia: stores “authorized” by Arab Computers stores and “independant” stores (itechia, ADAM, apparently Global Store and others). AC Macs appear to be European based on the power adapter while the others import from the United States.
The other choice as I said earlier is to buy from Amazon then ship using MyUS or similar services. You should assume paying for shipping as well as paying the Saudi Arabia custom fee (%5 if you are lucky, they once considered my 3rd gen iPod a computer!). You will need to add Arabic letters yourself and warranty is a bit sketchy.
Here are the prices for the MacBook Pro models from Apple compared to the Saudi Arabia prices, assuming a convert rate of $1 = 3.80SR. Remember that you need to add shipping and custom fees:
MacBook Pro 13-inch 2.26GHz: on Amazon: 4,405SR. Here: 5,649SR.
MacBook Pro 13-inch 2.53GHz: on Amazon: 5,677SR. Here: 6,899SR.
MacBook Pro 15-inch 2.53GHz: on Amazon: 6,480SR. Here: 8,399SR.
MacBook Pro 15-inch 2.66GHz: on Amazon: 7,480SR. Here: not available.
