Can I use my credit card to order a copy of Public Domain Computer Programs for the Aeronautical Engineer?
You may use Visa, American Express, MasterCard or PayPal to charge your purchase. The cards called EuroCard that also have a picture of the MasterCard logo seem to work. You may place an order at the PDAS Store and your credit card information will be encrypted for transmission over the internet. If you want to place a credit card order by mail or FAX, include the card number, expiration date and the name on the card if it is different from that on the shipping address. If you live outside the USA, please check that your card can be used to place US orders. I occasionally get orders (usually from students) whose cards may not be used outside the country of residence.
