We have kind, caring customer service representatives that care about you and your order. We will do everything we can to satisfy you, as we want you to remain an Xtreme Math customer. A list of e-mail addresses is supplied for your convenience within the contact us area.


Billing and Payment

We accept Visa, MasterCard, Discover and American Express. There are no credit card surcharges. Please be sure to provide the exact name, billing address, and telephone number as they appear on the credit card statement. Incorrect information may cause a delay in the time processing the order. Orders that are shipped to an address other than the billing address listed with the credit card company require a temporary, alternate shipping note added to the account. Applying this note may also cause a short delay in processing time, but you will be notified of this. This note is required for first time purchases only and is used to verify that the cardholder is placing the order. This is for your security. Please note that we will accept credit cards with verifiable account information with the Card Issuer. In the event that the Card Issuer is located outside of U.S., we may not be able to process the order. All transactions are subject to verification for safety and security purposes.


We also accept cashier’s checks, money orders, personal checks, and purchase orders. Certified funds and personal checks must clear before a product ships. Please contact our Sales Department for more payment information.


  • Terms will be Due Upon Receipt on the first three orders, then Net 30 days from the date of the invoice once the account is established.
  • Accounts must be current before subsequent shipments will be made.
  • Extreme Math reserves the right to accept or reject all orders based on our terms and conditions, which supercede any terms and conditions on buyers’ purchase order.
