Apple Petition for overcharges

This is a petition against how apple charges customers tax after the checkout of iTunes and the app store. When you purchase digital product and check out you have to enter a password then a confirmation for the price pops up. However this is not the actual price you are billed. I and millions of others are letting apple charge you tax after your transaction is complete. For example if you purchase a item for 19.99 you have to confirm the purchase most of the time with your password. However when you get your bank statement tax is included on top of the 19.99. This is illegal. You cannot be charged what you don't agree to. Regardless if apple has to charge you tax it must be calculated at time of checkout and conformation. Regardless of how much more programming is required to add the total beforehand its still illegal.
Please sign this petition to have apple fix the total amount before confirmation as well as give us back our extra charges we never agreed to without confirmation.
Please let others know about these transaction charges,
I don't mind paying taxes but we must all be informed at time of checkout of total price with tax if any.
