You are asked to pay online when you place your order, using VISA, MasterCard, American Express, or Discover. Our credit card processor is Elavon Converge, through their affiliation with Costco. We have no way of processing payments made by check, money order, or other online services.
We never see any of your credit card information. It is sent from your browser via an encrypted SSH channel directly to the payment processor. It is never sent to us, never revealed to us, and it is not stored anywhere in our computer systems.
We refund excess payments (usually this is because the shipping calculator over-estmated your shipping cost). We refund promptly if your order cannot be filled. All refunds go back to the credit card that was used to pay for the order.
