In the iTunes or App Store apps there is a Redeem button at the bottom of the page which is used to add an iTunes gift card.
iTunes gift cards and App Store gift cards can both be used to buy apps.
I think that you can, but I'm pretty sure you would have to do it on iTunes Store which is on your computer.
Scrolling to the bottom of the page in the App store reveals a Redeem button which is used to redeem an iTunes Gift Card.
Redeeming is entering the code on the card you buy from the store into iTunes. This money is used to buy content from the App Store.
An app store code is a code that you redeem when you buy an Itunes gift card, located on the back of the card. The codes can be for any dollar ammount from $15-$200 depending on what the gift card value is. You can buy Itunes gift cards at most retail stores (vons, CVS, etc.)
