From MacUpdate:

MacUpdate has partnered with the 7 best selling Mac programs on mupromo.com. You can buy the bundle for $49.99 instead of $219.88, a savings of $169.89. This amazing offer won’t last long.

Your Deal: As the Mac community comes together, you collectively increase bundle sales. When you do, you unlock 3 bonus applications that become part of the bundle for free. When buying, you become the immediate owner of the first 7 applications: GraphicConverter, Fetch, iWOW, GarageSale, Cocktail, ProfCast, and Amadeus Pro. Then the Mac community unlocks 3 more applications into the bundle for free.

They are at 2296 bundles, 204 bundles from unlocking little snitch. When 5000 bundles are reached, Intaglio will be added to the bundle.
