We all know of places like fontspace.com that allow you to buy fonts for commercial use, but if you are thinking about buying a font you should consider homelessfonts.org because they are a foundation that has a collection of typefaces based on the handwriting of homeless people.

Homelessfonts is an arrels foundation initiative which consists of creating a collection of typefaces based on the handwriting of homeless. The idea behind these typefaces is for people and brands to use them in their announcements. All profits are intended to help the 1400 people supported by the Arrels Foundation.
