Stock Status Description extension is a very good improvement for displaying product stock status descriptions on the product page. With this feature you can add a multilanguage HTML content tooltip or popup window for each availabilty and Delivery status. With a mouse over/click the tooltip or window will be displayed. For the availability ‘In Stock’ status, the tooltip will only be displayed when the product is out of stock.

In combination with the extension Product Stock/Delivery Status you can also display stock descriptions on al other product list pages like Category, Manufacturer, Search, Special, Bestseller, Featured and Latest.
