To checkout, click on the Checkout or Shopping Cart links at the top of the page.
First, check that the items and quantities are correct. To update quantities, enter the new amount the the Qty box and click Update.
Express Checkout is available once you have set up a default shipping address and default payment choice for your account.
To select your shipping information, go to My Account in the top navigation bar, and select My Settings. There is a drop-down menu with all of your shipping addresses and another drop down menu with your default payment choice - select your defaults and click Save and Continue.
From the Shopping Cart/Checkout page, clicking on Express Checkout submits your order without any other steps (not even an order review page).
This option is available if your company has set up an account with us and arranged for company billing. If this is the case, when you check out you will see a Pay Without Credit Card button. Clicking on the Pay Without Credit Card button will set this order to be charged to your account, and you can continue with checkout.
