How do I add a Purchase Order number to my online order?
When you are placing an order, navigate to the cart page by clicking the Cart Icon in the top right corner.
When you arrive on the cart page, scroll down until you find the blue hyperlink that says "Add Special Instructions To Your Order". Click this link, and a dialog box will open below. You may add your Purchase Order number in this box.
Proceed through the checkout process until you get to the "Payment Options" page. You will see an option for "Purchase Order". Select the Purchase Order radio button, then complete your order.
