Payment is due on receipt of invoice .
We must receive payment by check, money order or credit card in U.S. dollars before we ship the order unless other arrangements have been made in advance. If mailing your order, be sure to include type of card, card number, expiration date and signature. We discourage emailing your credit card information, as we do not have a secure server. Please reserve credit card use for our secure online form , phone, fax or mail orders only. Most courses have several tapes and these can be ordered on a delayed basis.
