Aside from checking the card account itself , where do i view my apps expense so far on the Pad ; i've looked every nook & cranny .....no clue

If you view your account in iTunes on the computer you can look at your entire Purchase History: though not all at once. Mine goes back to 2003.

The small arrows to the left of each entry allow you to expand it for more details.

Thank you so much....

you are welcome
