1 hour ago I've spent 160 k Nanas in AppNana on 10$ iTunes gift card.I have received the confirmation mail,currently waiting for the code,the gift card is only valid in US store. I've made an US account a long time ago with "None"payment method. I'm curious if redeeming the code and buying the apps on gift card cash will work since my payment method is "None",so I am not using any credit cards on this account. Will it work?
