To start the check out process just click the “View your shopping cart” button located in the upper right of any page. This will bring you to a page to input some more information so we can finish the check out process.
If you have any trouble with the cart, we have a backup site where you can order the add-ins from as well. It uses a completely different web host with a different credit card transaction processor. You’ll have to start shopping all over again, because your cart will not transfer to that site, but at least you’ll be able to order the add-ins.
