We accept Visa, MasterCard, American Express, Discover, as well as Government cards. Credit terms are available to qualified customers after approval. All initial orders must be paid by credit card, unless other arrangements have been made. Due to fraudulent credit cards we no longer ship outside of the United States. The system will not process any orders with an invalid e-mail address. If for any reason you do not want to use your e-mail address, the orders must be placed with us by telephone.
