Apple raises the prices of both the Apple iPhone 5s and Apple iPhone 5c in France
The reason for the price increase has to do with changes in the foreign exchange market that reduced Apple's profit margin. Most likely Apple was getting fewer dollars back for the Euros it was receiving from the sale of the Apple iPhone 5s and Apple iPhone 5c in France. Apple recently did the same thing with paid app prices in the Japanese App Store, raising prices on Thursday to make up for a weaker Yen.
