I will be visiting Dubai next week for diplomatic mission. Though I will be very busy in my mission I would like to buy duty free electronic products in Dubai, certainly if there are any online stores for the same it will make my task easier.

There’s no duty on electronics/PC parts in Dubai as far as I know. Though they’re still not cheap (if you’re looking for tablets/phones). If you’re looking for PC parts or laptops, I’d suggest you head down to Al Ain Centre in Bur Dubai anytime in the evening and have a look around.
