Once you complete the registration screen and/or add merchandise, your items will be added to your shopping cart (located in the top right-hand corner of the screen). You may add additional car registrations, vendor registrations, sponsorships, and/or merchandise to your cart, allowing you to check out and pay only once.

Your registration is not complete until you finish the checkout process and submit payment. Once completed, an order summary will appear, and you will receive an email receipt.
