You're much better off using the Walmart App, but I have not seen Prime available in the last couple of weeks.
Just open this link on your mobile device and if you have the app installed, it will open in-app. You can then add to your favorites to create a watch list. You won't get any in-stock notifications but you will have a much faster way to check stock.
