Payment Methods

During checkout you may pay by credit card (Visa, MC, Amex, Discover), Paypal, check or money order.

When paying by check, complete your checkout online like normal and select "Check / Money Order" as your payment option. When we receive your check, we will apply your payment to your order already in the system and begin processing the order.

Google Checkout payment is also possible if you contact us, although it isn't part of the normal checkout system and must be done manually.

Call us at (510) 868-0597 to pay by credit card over the phone (Visa, MC, Amex, Discover).

We can accept purchase orders by fax, email, snail mail, or online with the "Check / Money Order" payment option described above. Purchase orders are accepted from government agencies and government-funded educational institutions including high schools, colleges and universities.
