Why does electronic devices in Turkey cost much more than other countries?

For example an iphone 6s would cost 700 dolars (roughly 1.700 turkish lira) but when you look at the turkish apple store it says 2.600 turkish lira. Plus if you buy from another country you have to pay an arm and a leg to get it from customs. Why?

Turkey does not allow importing them from other countries

Because all these garbage governments drop on so many taxes and fees and then try to alter their currencies which makes its great for them to collect money but bad for all the people.
