Apple has just launched its annual 12 Days of Gifts campaign for 2013. In previous years, this campaign was available only in a few select countries, but not in the United States. For the first time Apple will now allow U.S. customers to participate in the giveaway. The 12 Days of Gifts app is available for free on the iTunes Store. Each day for twelve days the app will provide a special free item from the iTunes, iBooks, and App Stores. Each gift is only available for 24 hours, so users have to check in every day to make sure they get everything that’s offered. This year the giveaways start on December 26th and run through January 6th. Here’s the description from Apple: “From 26 December – 6 January, you can download a gift each day—songs, apps, books, movies, and more—with the 12 Days of Gifts app. Each day’s gift will only be available for 24 hours, so download the free app to make sure you don’t miss out.”
