Goodies is a Mac OS X application that helps you organize your online shopping. In one simple step you can query various online retailers, see tabbed results, easily compare all deals, and assign your goodies to groups, based on your budget, deadline, tags or projects.
Great App! (...) This is the best, most convenient way to manage lists and comparison shop. It is especially helpful for keeping personal projects under a budget as you plan what you need (home repairs, remodeling, etc.). So many apps like this fail by making things overly complicated. (...) This one actually saves time and helps make planning how you spend your money a lot easier. It combines research and calculations into a single place.
