Why does Itune keep taking money from me?

If there not taking money from me for no reason then there charging me to much. I don't believe iTunes charges tax so when I buy 1 song 1.99 & 1 episode 2.99 how does iTunes get $11.50 out of that? Today they took out $8.98 and I haven't been on iTunes in weeks nor did I by anything songs, episodes apps nothing. This never happen until I got a IPhone

Try removing your credit card info from your account. That way they can't charge you if they don't know where to take the money from.

That's a good idea I don't know why there doing it but i'm not the only one. There a big company so why rob random people. Ill just buy & use the gift cards so they stop taking my hard earn money.
