Total CostThis total is based on the price of materials at the time this teacher submitted his/her project. Actual expenditures may differ slightly from the above estimate due to items going on sale at time of purchase; the need to use alternate suppliers when the original items are out of stock; and/or the absence of payment processing charges for donations by check. If actual expenditures turn out to be more than the above estimate, DonorsChoose.org pays for the difference. If actual expenditures turn out to be less than the above estimate, DonorsChoose.org places the savings in a restricted account to fund additional classroom projects. In short, any savings go to students.
