Where should i buy my macbook?

i live in abu dhabi. the macbook 2.4GHz here is AED 6835. but in amazon it is USD 1567 (AED 5754). im not worried about transport charges since im going to order it to usa and my uncle will bring it. so should i buy it in amazon? if there is any problem, will the iStyle shop check it out for me? thank you in advance.
