The Out of Stock Notification extension developed by M-Connect Media to help the web-store owners in informing their customers about the stock status of the products which are out of stock. This makes the purchase or planning to purchase any out of stock product easy for the customers. When any product is out of stock, the customers can see the out of stock appear on the product details page. The customers will get the option of subscribing to the email notification with subscribe to back in stock alert message and a field to enter their email address with subscribe button. The store owners will be able to manage the notifications list from the back end.
