We understand that some people would prefer not to use PayPal. If you would prefer to mail a check or submit a purchase order number for an institution we will be glad to accept orders by postal mail. To facilitate this, here is a link to a PDF order form that you can print and mail to us with a check.
Educational institutions may submit the form with a purchase order number.
NOTE: You do not need to have a PayPal account to use your credit card with PayPal, just go to check out and follow the steps to enter your credit card number. Currently PayPal is the only way that we can accept credit cards.
Thank you for your interest!
