I recently made an in app purchase from my iTunes account in which the account was over charged by .49 cents. I thought it was simply an error in my calculations, so I made a deposit to my iTunes account by redeeming another iTunes card and taking the time to write down the balance before making a purchase. I made the same purchase twice for $7.99, with an added sales tax of $.52 bringing the total to $8.51. I was charged $9.00 for two transactions that should have only cost $8.51 according to the E-receipt. Claire from iTunes claims I am confused, is anyone else having a similar issue?
