Using itunes gift card

On the right side of the main store window, the first box is "quick links". In that box, click on "redeem" & you should be able to redeem your card.

the quick select catagory does not show up on my screen what do i do?

In iTunes, select the Store. Look on the right side of the main iTunes store screen.

i do the exact same thing! it's very easy-- just open up the iTunes Store then on the upper righthand corner, there should be a quick links box. it has the browse, powersearch, etc options inside of it. click "redeem" and that will take you to the page where you can type in the code on your iTunes card. once you do that, you'll have to create an account then you'll be good to go!

After you enter the card umber, it will ask if you want to a create new account or use an existing account.
Select Use existing account.
