MDUSA accepts purchase orders from all schools, universities, and the military. Purchase orders can be placed online with a purchase order number but a signed purchase order from the organization also needs to be faxed or emailed to MDUSA. An organization can also receive quotes for larger orders. Please contact us at 803-835-6853 or email us at firstname.lastname@example.org to receive a custom quote or to email a purchase order. If you need to fax your purchase order our number is 803-802-3258.
