Last year, on the Appstore’s first birthday, Amazon celebrated with an entire week of discounted apps. This time around, you have a smaller window to cash in on the occasion. The free apps will only be free for today, Friday, March 22nd.

Amazon’s Appstore launched on March 22nd, 2011 and almost immediately pissed off Apple, who ended up protesting Amazon’s use of “Appstore.” Now, two years later, everything has been settled and the world is still spinning on its axis. Here’s to many more years, Amazon Appstore.
