DropDMG is part of the Give Good Food to your Mac “Special Developers Edition” promotion:

“Give Good Food to your Mac” is a community action where independent Mac developers come together and build exciting promotions: for a limited time, every Mac user will be able to download and taste cool Mac applications and enjoy great discounts.

No junk food, just healthy, tasty and innovative products. And because we are speaking “haute cuisine” everybody gets to create their own combination of titles matching their own and unique taste.

From June 9–23, you can get discounts from 20–50% on a variety of great tools for Mac development. In fact, many of the applications (including DropDMG) are also useful for non-developers.
