Basic Ordering Instructions: To purchase a title, click the "Add to Cart" button for that item. Clicking "Check Out" takes you to our Secure Order Form, where you will have the opportunity to select from a variety of shipping options and payment options, including credit card and purchase order. On the first page of the secure order form, you will type in shipping information and billing information. If ordering by credit card, be sure to enter your credit card's actual billing address in the billing info area. To complete your order, don't forget to click "Continue" and then to click "Place Order". You'll receive an immediate e-mail confirmation of your order. All school direct-ship orders must be prepaid by credit card or PayPal, carefully follwing the checkout instructions (selecting the proper method, and entering the card information in the proper field). Thank you!
