Well.....Yes and No....
Even in cases where the Developer keeps both up to date the Amazon App does not automatically update you and will not always notify you of one until you run their App...
Google will almost always automatically update you to the latest version except at times where the permission requests have changed significantly enough to require manual accepting of the new permissions.
And if your flashing custom roms a lot the other thing about Amazon is that unless the app is installed it not only won't update but the license will expire until you log in to Amazon at least once after every flash.
While it's nice to save money for the $3 or $4 I prefer to get most (if not all) of my Apps from Google.
But I sure understand why people are willing to go through the extra hassle to save a few bucks in this economy.
