There may or may not be creatures stirring at Amazon's house this day before Christmas, but the people are busy offering up their usual selection of deals preceding most holidays. The Appstore's free paid app of the day has been extended to no less than 40 apps and games today. Here's the full list, which may or may not be limited to users of the United States version of Amazon's app portal (and a couple are exclusive to the Kindle Fire or Fire Phone):

Apps

Games

Oh, and there's one more free app to check out: the storybook app of How the Grinch Stole Christmas. (The real one, not the Jim Carrey version.) It's free for the next 13 hours.

All of these apps are free for today only. Head on over to Amazon on the web or via the Appstore app on your phone or tablet to link them to your account.
