If you’re using the Legacy Version (V1) of Make an Offer, you can show the Make an Offer button even when a third-party pre order button is present or the product is out of stock.
Here’s how:
In the Make an Offer admin section, click on Setup.
Choose the Incentive Configuration tab.
Make sure the Pre Order/Out of Stock (Mobile and Desktop) toggle is turned off.
Scroll to the bottom of the page and click Save.
This setting is only available in the Legacy Version (V1). If you need more help, please contact our support team.
