Appbuzzer offers its members downloads of its Appbuzzer Celebration Bundle for free upon Tweeting about the bundle. (Click the "Get Now" Button; you'll also need to enter your social network login information.) That's a $93 savings compared to paying the list price for each program and the biggest bundle we've seen Appbuzzer. It includes MainMenu, Corporate Style Packs: Enterprise, Vinyls, SnipEdges, Papier, Cockpit, and more. Deal ends July 4.
