Habitat for Humanity
One of the many great things about Habitat is their ReStores, where they sell materials that were left over from projects and/or donated materials that they cannot use in their projects.  This is a great opportunity for volunteering, as well as finding home building and repair materials for your own projects, whilst support some seriously wonderful work.
