About this app
Sink automatically pushes out-of-stock products to the bottom of your collections, so shoppers always see available items first. When a product is restocked, it moves back up on its own. You can also sort each collection with rules like Best Selling, Product Title, or Price, or set your own manual order. Sink works with any theme, needs no code changes, and updates collections in real time as inventory changes—keeping your store organized without any manual effort.
