ReStore, a division of the international organization Habitat for Humanity, sells used and surplus building materials to the public. The retail operation's profits raise money for local building projects (per the organization's goals to provide housing for lower-income families).
According to the group's Facebook page, its mission is "to serve throughout Portage County by working with qualified persons with housing needs to help them create a better human habitat in which to live and work; and cooperate with other charitable organizations, through donations, grants and other resources, to develop a better habitat for God's people in need."
Call ahead to discuss any potential donations. In some cases, pick-up can be arranged.
