Question 9: I would like to remove any out-of-stock products from the Bought Together list automatically. How to do that?
Answer: You can also go to WPClever >> Bought Together >> find “Exclude unpurchasable” option then choose “Yes”. When any products go out of stock, it will be removed from the list in the front-end.
If you choose “No”, out-of-stock products will still be visible, but buyers cannot choose or add them to the cart. There will be an alert for the out-of-stock items.
