Purchasing Agents: If you have received an invoice, please remit payment to the address on your invoice.

Documentation Fee: If you would like to order online using a corporate or university credit card, please make sure to include the $100.00 documentation fee with your first order.

This is a one time fee that covers the cost of the additional paperwork that we are typically asked to fill out after school, university, or corporate orders.

The documentation fee applies only to schools, universities and corporations within the United States.

You don’t need to pay this fee if you order with a personal credit card.
