Extras are simple add-on items sold next to your meals - snacks, drinks, shirts, training or coaching sessions - each with a name, price, description, images and optional stock tracking. Customers buy them on the Extras page and, optionally, from the cart preview. The page lives under Ordering > Kitchen > Extras (/admin/extras) and only appears when the Extras module is active; it is sold as the Extras Ordering System add-on under Support > Addons (listed at $25/month in the current version).
