Can I use a iTunes gift card?

I just got a $15 iTunes gift card and I want to spend it (duh!). My question is this : can I use it to buy a premium membership here at chess.com? Like if I wanted to buy a one month gold membership, can I use my iTunes gift card, or does it get charged to the credit card I used to set up my apple account? When I try to buy a premium account in the iOS app, it asks me if I want to confirm the purchase, just like it does when I buy something else in-app. I know that it just comes out of my giftcard on others in-app purchases, but I didn't want to buy it before I knew the answer.

Also, will this work for google play as well? I couldn't find an answer to this in any other forum, so if it has been answered already, my apologies! I would like a premium membership, but don't want to use my credit if I can just use the iTunes gift card. Thanks for your time!

This post is resolved.  I bought a one month gold membership on the app, and it took it out of my iTunes credit.

Hi, I got 2 15$ iTunes cards for Christmas. I put them on my iPod thinking I could purchase a membership with them and it won't let me enforcing me to use a credit card. Is there any way around this? Thank you.

I have something like 49.61 on it and it's 48.99 something like that for it and it says insufficient in store credit

      This seems like a no brainer; iTunes gift cards can be used at the iTunes site. Chess.com uses major credit cards, and pay-pal.

I used it to buy a 1 month membership. I'm assuming I couldn't buy the 1 year membership because of taxes.

With the chess.com app on the iPod

      I stand corrected; thank you Thomas G Robinson!

Then you have to buy the rest of the more using your credit card, Thomas. You will need to input a credit card number to buy things - its just how iTunes works.
