Also, do you know if I can use it on my iTunes account that is linked to my debit card?

100% you can

Uh, how do you work that then? How does it tell the difference between a debit transaction and a card transaction? (Also sorry for my 2nd post, I didn't fully read the op.)

@japster When you get anything on feature points then it's just like you're redeeming a gift card. For instance if you get an app then you get a special code you put into the gift card thing that will automatically download the paid app for free! Gift cards work the same way! Clash on!

I know how adding gift card works, I would like to know if I can do it on my current account, which is tethered to my debit card?

I'm level 71, gold town hall 9, my names sonic. Can I join?

I wish I could use it, but I am not in any of the countries you have mentioned.

Mariovt, yes allthough it is off topic and you have probably found a clan on global by now. clan name is KING KONG

YAY!!!!!!!!!!!!!

Japster I'm 99% sure that it uses up gift card credit on the AppStore before debit purchases
