When your customers love an out-of-stock item, create an option for them to be notified when it’s back in the store. Asking people to get on the list creates urgency. When the item returns, you want to persuade customers to make that purchase more than ever, using verbiage such as “Get it now before it’s gone,” “While supplies last,” and “Limited quantities available." Help guide customers toward purchasing the item so they don’t miss out before it’s gone again. Show them the value in returning to buy the item.
