How do you check how much money is in my itunes account?

I have a 5th generation iPod touch and to check how much money you have in your gift card, go to Settings. Then scroll down to iTunes & App Stores and tap that. Tap the first one that says Apple ID: (username) and a pop-up will show. Tap View Apple ID then you will be required to type in your passWord. After you type in your passWord, at the very top of the page it will say Apple ID Balance: (Amount of money). And there you go!
