Corporate Warehouse Supply is based in Superior, Colorado, and offers copier supplies, primarily toner cartridges, to businesses around the country. In order to give back to the larger community, Corporate Warehouse Supply participates in a program called Recycle4Charity, which accepts donations of empty printer cartridges to raise funds for a variety of charities. Through this program, Corporate Warehouse Supply contributes to ChildFund International, an organization that supports children around the world. In 1938, Dr. J. Calvitt Clarke founded China's Children's Fund to assist orphans in China. Child sponsorship, the primary method the organization used to support children in poverty, asked volunteers to donate to one specific child. In 1951, the group adopted a new name, Christian Children's Fund, to reflect how its efforts had spread to more than 50 countries. The organization merged with 11 other international children's organizations to become ChildFund International in 2002. Today ChildFund International assists children in poverty and their families as well as those dealing with crises, ranging from illness to natural disaster.
