-You may use PayPal for your purchase by sending funds to our email: Please check with us by phone or email first, to get the correct total, including shipping charges, and tax if any.

Shipping charges vary substantially by product, destination and customer requirement. Our policy is to charge only an amount to reimburse our costs for shipping, handling and insurance. We are happy to provide individual shipping quotes, tailored to the needs of each of our clients, by phone at 510-282-9300 or 800-634-0094, or by email to

We are obligated legally by the State of California to collect sales taxes ONLY on orders that ship to California addresses. We charge only the rate that is applicable to your county/city. This can be difficult for a buyer to determine accurately, so we suggest that you phone or mail us to find the correct amount before making the check or money order. When we ship to addresses outside of California, we do not charge any tax at all. Please note that non-USA shipments may be subject to local taxes, duties or fees that need to be paid to local authorities in the destination country, at the time of delivery.
