Ya as with most shopping one should do a little research
I'll give you an example
Macbook Pro 13 inch is only 4600 at Comp. Plaza, which is a great price and close to the American one.
Samsung 4 series 32 inch telly was 1300 at the last shopping festival, which is cheaper than even Amazon in the UK.
When the exchange rate was around 6 it was even cheaper.
Anyway, that's just examples.
My Nespresso machine was 150 in the UK, got it on sale from John Lewis for 100, with 30 quid rebate (net price 70)
Here the same machine is 1500 AED!! Needless to say I packed it with me and brought it down
One just has to be careful, but there are still deals to be had
