As a regular donor to this organization since 2008 I support its goals and have no objection to the executive compensation and the 15% project surcharges criticized by other reviewers. However, I am often dismayed at the sources DonorsChoose and the teachers use for requested items. Technology projects in particular are often overpriced and poorly specified. Flash drives, printers, laptops and projectors are sourced at national retail chains like Best Buy rather than equally legitimate online discount suppliers such as TigerDirect, Dell Outlet and Newegg which have far lower prices and better selections. I wrote to the charity about this and they responded that their stringent vendor requirements miss some discount prices but save money in the long run. When price differences are routinely 30-50% and sometimes up to 70% on packages costing hundreds of dollars, that doesn't make sense.
