I'm looking at buying an iPhone 6 in Japan over christmas, and I'm a bit annoyed to see that there has been a price hike. On release it cost 67800 JPY and now apparently they've increased the price to 75800 JPY. Is there any particular reason to why they increase the price, and would it by any chance drop until december? I know the boxing day sale is after christmas, so is it perhaps more clever to buy it then, assuming there might be a discount? Also is it still possible to shop VAT free as a foreign national?
