Hi if you want to get the best deals; and have family/ friends in the USA then it seems to be the best place to get stuff from.

Personally I was under the opinion that Singers/ Hongkong and Dubai were the best places to source stuff. But take a look at this link

Dubai made it to No.5 on that list - plus its proximity to Qatar means that you can get it on a business trip.
