Consequences of poorly performing GBP and Euro.
In the comparison I have used current exchange rates. GBP or PLN don't have a tendency to drop down by 10% overnight. I also do not see the reason why Apple couldn't offer the option to charge in USD, in Europe many banks offer currency conversion without fees for online card payments, such as Monzo in the UK.
Someone else mentioned that warranties are required to be longer in the EU, which would increase the OEM's operating cost as well.
1. Maybe it's not UK vs. Poland difference, but UK vs. EU difference?
2. There may be less iPhone users in Poland, so the prices reflect lack of economies of scale?
