Home: This is the home for a specific category. The category selection is a roll wheel style where the user can scroll through and pick what category they want, then the items appear on the right where they are allowed to scroll through that as well.
Individual: When you select an item, a further description opens up, and a back button just in case the user doesn’t want that item.
Checkout: Simple table-look giving a quick rundown of the items in the cart. Hitting checkout takes you to the generic “fill in your information” page.
Complete: A simple confirmation page letting you know the order is finished and the option to go back to the home page.
