Back in February, we told you that Order of the Phoenix was the first Potter movie available for purchase on iTunes. This month, not only did iTunes enable the option to rent OOTP, but Chamber of Secrets is now up for purchase.
You can buy the movie for $9.99 and play it back on your computer, iPod, iPhone, or Apple TV. We'll let you know when the other Potter films make their way onto iTunes. Thanks to John for the tip!
