Guest order flow

What happens behind a guest order, in plain terms:

1. Checkout opens without a login. Your store allows guests, so the shopper goes to Your details instead of the login page.
2. Details are checked. Email must look like a real email, name cannot be blank, and phone must be filled in if you made it required.
3. The cart is re-checked. Prices, stock and coupons are worked out again on our side, so a shopper cannot change prices in their browser.
4. The order is created with the guest's name, email and phone on it instead of a customer account. Coupon usage limits count guest orders too.
5. Payment. Online payments go to your payment gateway as usual. COD orders are placed straight away.
6. Emails. The guest gets the order confirmation and later status emails (shipped, delivered) at the email they typed.
7. Abandoned carts. If the guest typed their email but did not finish, Abandoned Cart can send them a reminder.

A guest can only look up their order with both the order number and the email used. Nobody can see an order from the number alone.
