As a benefactor of DonorsChoose, I know how meaningful it is to receive donations in order to get a project fulfilled. DonorsChoose is an organization that allows teachers to propose projects they would like to get funded through donations. Groupon has linked up with Pershing Square Foundation to create a great deal. Pershing Square is donating 60% of the $25 when you buy $10! Check it out here! If you're new to Groupon, sign up here. They have some great deals!
