We accept Visa, Mastercard, AMEX, Discover, and Paypal.
We only accept purchase orders from qualified educational and governmental agencies in the U.S. with a minimum order of $100.
If your institution qualifies to submit Purchase Orders, simply add items to your cart and select the "Purchase Order" option on the payment screen.
Once your order has been placed, email a copy of your purchase order to firstname.lastname@example.org
Your order will NOT be shipped until your SIGNED purchase order has been received. Orders will wait in our Pending Orders Queue until a signed purchase order has been received. You may receive a notice or your order may be canceled if, after 30 days, no signed purchase order has been received.
