guys can i ask a question?
i read from the front page says we can purchase games by buying itunes gift cards.

my iphone is bought from australia. so i created an account which is addressed to australia as well.

now if i wanna purchase an app, the easiest way is to create another itunes account (for msia) and then charge it thru my credit card?
also i noticed in garage sales, currently there's no one selling itunes gift cards.

if i charged to my cc, let's say the app is $3.99, so i'll be charged the exact amount? rather than to purchase $15/$25 cards and just use up $3.99?

i logged in my phone account based on an address in australia.

i heard from a friend that if i would to create another account (malaysia) and purchase the app, i would not be able to sync/share/play that app when i switch my phone back to australian account.

yes.. thanks.. i went through that.
i know i can have multiple accounts, just need to confirm apps can be used in multiple accounts..

thanks for the answer
