Apple has added a section to the App Store that allows you to quickly make a donation to the Red Cross and Hurricane Sandy relief. 100% of your donation will be transferred to the American Red Cross by Apple. The process is super quick and super easy.
You will find the section in the Featured tab of the App Store. When you first tap on the new section, you will promptly be asked for your password. Entering your password does not mean you are committing to a donation, but simply allows you access to the donation screen. Donation amounts include $5, $10, $25, $50, $100, and $200.
