First, check the stock list for current prices, availability, and current estimated delivery times (note that multiple module orders may take longer). Please be sure to read the Terms of Sale before placing an order.
Then, email your order to firstname.lastname@example.org with your FULL NAME, BILLING AND SHIPPING ADDRESSES, and TELEPHONE NUMBER. You will receive an invoice within 36 hours for the modules you specify. In the case of "built-to-order" modules, you will be invoiced for a 50% deposit up-front, and the balance + postage upon completion.
