In one sentence, describe what the following article is about:

If you were sent a gift card by email, there is no need to print it out. Amazon gift cards are widely distributed via email, Facebook and plastic card. This is a 16-digit number on the email receipt or on the back of the plastic gift card. If you are using a plastic card, you may need to scratch off the strip of coating to see the number. If you don't have one, you should create an account and confirm it using your email. Unlike other gift cards, Amazon's cards are stored in your online account once entered, instead of on the card itself. Click the link that says, "Apply a Gift Card to Your Account." Once you are finished, click "Apply to your Account." The gift card balance will be applied to your account and used on your next purchase before other forms of payment. You can apply it during checkout.
Find your Amazon Gift Card in physical or virtual form. Look for the claim code. Sign into your Amazon account. Click on "My Account" in the upper right hand corner. Enter the 16-digit claim code. Opt to enter the claim code when you make a purchase, instead of applying it to your account if you plan to spend the whole thing immediately.
