We accept payment via credit card, check or money order, and AP member assessment. We will ship your books or activate your subscription once we receive your payment. We do not accept purchase orders.
Our order form does have a place to add in your purchase order number, if you like, but this is only for your record keeping.
The order form will allow you to calculate your total charges, indicate your preferred payment method, then click on "create an invoice" to generate an invoice to include when you mail in your payment.
