2. Payment & Taxes

Is ordering online secure?
Yes. We take the utmost care with the information that you provide us when placing an order on our website (or through any other means). The server that hosts our bookstore encrypts the transmission of all credit card and personal customer information using the Internet-standard SSL (Secure Sockets Layer) protocol. During the encryption process, information is scrambled into small bits of code that cannot be read as they travel to us over the Internet. Once we receive the encrypted information, we use a private, one-of-a-kind key to decode it.
All of the information you provide during the ordering process is restricted to our staff, and we make sure that all of our employees up-to-date on our security and privacy policies. If you have further questions about the security of ordering online, please feel free to e-mail us at

What are your payment options?
We accept all credit cards, as well as checks and wire transfers from incorporated organizations.
All checks submitted for payment should be made payable to “Bertin Corp.” Note that checks must be written in U.S. Dollars and must be drawn from a U.S. bank. Any international checks received that are drawn from an international bank will be returned.

Will I be charged sales tax?
State Tax is collected in the following states: MD and CA.
If you are tax-exempt, please place your credit card order as you normally would. We can only credit the tax amount back to the card used on your order after receipt of your tax exempt information. Upon completion of your order, you will be given an ‘Order Number’. Please email a copy of your ‘Tax Exempt Certificate’ (or reasonable facsimile) and ‘Order Number’ to:
