As reported abroadly by media, we also were noticed by Apple that the app store price will be adjusted in next 36 hours.

The email, sent out Wednesday, said Apple will raise prices in its Canadian App Store by Friday to offset the eroding value of foreign exchange rates and adjustments in value-added tax (VAT) rates. Within the next 36 hours, therefore, prices on the App Store will increase for all territories in the European Union as well as in Canada and Norway, decrease in Iceland, and change in Russia.

Just for your reference.
