Important: The practice of nesting another step in one step makes the user feel confused and fearful because it is inconsistent with the mental model of the user's linear operation when they complete the payment.

In these sites, Wal-Mart and Zappos are using a non-linear cashier process. Both are nested another branching process in their payment process. For example, let the user set a "Preferred shipping address" (Wal-Mart) or "Create a new Account" (Zappos) on another page, and then return to the original page to continue paying. The following is a screenshot of Wal-Mart's operating procedures, click on the picture to see the complete process.

Luckily, it's easy to get the cashier process linear. For example, after completing the "Create your account" branching process, never relocate to previous pages and processes, but instead use direct guidance to the user for the next step.

Remember that the most important point is that most users pay when the mental model is linear operation. If you see the same page two times, you will usually think that the site is faulty or that you have done something wrong.
