Pretty crazy arrangement they have with developers. But the down side is no auto updating and you might not be able to access stuff later on if they discontinue it but as they say free is free.

Source - Over 100 Paid Apps For Free On GetJar | xda-developers

GetJar, an independent application store for Android, is offering 100 paid apps for free.

The process of downloading and installing is a bit cumbersome, though ? you need to install the GetJar app first, and you won?t be able to update those free apps automatically through the Android Market. But still, free is free, especially since there are some real gems in the selection, which we?ve picked out for you:

Beautiful Widgets
Splashtop Remote Desktop
Tapatalk
TweetCaster Pro

And some cool, high-quality games:

Fruit Ninja THD
Age of Zombies
Orbital
Glyder 2
Quell
Cross Fingers
Side-note: NFL 2012 and Duke Nukem HD are currently free on the Android Market

Grab GetJar from your phone - m.getjar.com

Tapatalk is useless until you log into the site your browsing, not bad but i still prefer using a web browser.
