Candy Cart gets the real-time data that is available from your store and then displays it.
If a product is out-of-stock while setting up an upsell offer for it, the application will show an error, and will not let you save the offer and display the product in the app.
Also, if any of the upsell products gets sold out while the upsell offer for it is active, the app will stop offering it to customers.
