A category page before and after: sold-out products move to the end.
Shoppers who land on a category full of “Out of stock” badges leave. InStock First keeps what you can actually sell at the top: in-stock products are shown first and sold-out products move to the end of the list, without hiding them (so you keep their SEO and customers can still sign up for restock alerts).
It works the moment you activate it. There is nothing to configure and nothing to re-run: the order is applied when the page loads, so a product that comes back in stock moves straight back up, and a product that sells out drops to the end on its own.
InStock First does not collect, store or send personal data, and it makes no external requests.
