Regarding inflation in the UAE, there is a perception that if you only eat out monthly not weekly you should be somewhat protected. When I visited, the discount card brought it down to something sensible (not too bad when paying for just yourself). Otherwise yes it was expensive, in particular alcohol.
Certain groceries/household items seemed twice or three times as expensive as in Europe (toilet roll, potatoes!). Other daily stuff - coffee in malls, lunch, seemed exact same price at EU for now. Internet in EU is about 25 euro a month, I heard its over 100Euro there.
I guess buying a new car is tax free, saving a fortune on EU prices, and interest free, using their car loan facility. Or just get by on cheap taxis for first couple of years (one less debt to clear if needs be).
Any examples of extreme ongoing inflation to be aware for budgeting? Things you didn't budget for before going out there? At some stage rising inflation will cancel out the tax free gains... dont think its there just yet?
