Payments for schools

Cheng & Tsui is happy to invoice schools with an existing account for their orders, provided we receive an official purchase order in writing. Schools may also pay with department credit cards (MasterCard, Visa, or Discover), personal or school checks, or money orders. All payments must be drawn on U.S. banks in U.S. dollars; make checks and money order payable to Cheng & Tsui Company. For credit card payments please provide the type of card, the card holder's name, credit card number, and expiration date.
