From Fundable Group:
Fundable.org lets groups of people pool funds to make purchases or raise money. Similar to online auctions, Fundable's pages, called "group actions," are created by people who use this site. Each group action has a description of how much money needs to be collected and what it will do. Once enough pledges (not payments) have been collected, Fundable turns them into real payments and sends the total to the group action's organizer.
