In this video we will show users of the Walmart app how to pick a substitution if items should be low on stock. If items should be low on stock after you’ve placed your order you will be given a notification to edit substitution preferences. On the next screen click on edit under each item. There you can choose to replace it with the best item, pick a certain item to replace it with, or not to have them replace it at all. Once chosen click select. Then, once you’ve completed all substitutions click update order.
