Selling

Create a product, add its images, and use attributes to generate the variant matrix — including the one thing that trips everybody up: price lives on a variant, not on the product.

Read an order, and update its three independent statuses — where the order is, whether it is paid, and whether it has shipped.

Where customer records come from, what you can add to them, and which internal note never leaves the Manage screens.

Three kinds of discount, two ways to apply one, and the four statuses that decide whether a code works.

The base currency, compact display like "1.5 Million", offering several currencies to shoppers, and overriding all of it for one product.

The site-wide cart drawer, how to edit it, and the button actions that drive it.
