Locate REDEEM on right hand side
As you know iTunes has a fantastic system where you can buy music on one device and wirelessly download them to all your other devices .But they don’t make it easy for you to redeem your coupon. If you’re not careful you click ‘buy’ thinking there’s a process which will eventually ask you for your coupon code, and before you know it it’s downloading and you’ve paid without redeeming your coupon. So, open iTunes, go to iTunes Store, click on the ‘home’ icon at the top of the page. On the home page look under QUICK LINKS on the right and click REDEEM. This will take you to what you’ve been looking for the REDEEM CODE box and simply fill in your code.
