The UAE official Apple Store is now available. Looks like that the prices are more competitive than the local distributors.
I have already placed one order and saved a couple of thousands Dirhams. I can say that at least you will save between 10 to 20 percent on the local prices. The best thing of all is that you can have all the options and accessories that are available in the US because all orders are coming from there. You will no longer be at the mercy of the distributors and what is locally available.
