You can track the stock status for all products by subscribing to the "Global Product Notifications" option.
To do this, please go to your "General Information" and then "Product Notifications" page. From there, you can tick the "Global Product Notifications" option.
How can I find out when a product goes out of Stock?
All out of stock products are immediately taken off from the site. In order to keep a track of a particular product or products, you can sign up for the Product Notifications option for that product. So that when it goes out of stock, you get an email notification instantly, notifying that the product is now out of stock. This option can be found in the right pane on every Product Information page.
This option can be particularly helpful for Dropshippers, wishing to track the status of products being displayed on their sites.
How can we find which products are available for dropshipping?
Pretty much all the products that you see on the website are available for Dropshipping. Once you login to your dropshipping account, any products that are "Trade Only" are automatically hidden.
