When Pokémon X & Y released, i was trying to buy a digital version.I added 40 $ to eshop and when i was almost purchasing it, it said that the price was 41.99 (the main page said 39.99), so i bought 10 dollars more.With the change I got from that, I'm trying to get Pettit computer, but the same thing happens, i have 8, in the front screen it says 7.99 but when i try to purchase it, I have to pay 8.39. is there any workaround available ?
