Buy 3 items and get the cheapest one free: Magento 2

Question

I'm searching for at solution for being able to sell a customer 3 different product items and then getting the cheapest one for free. Can I accomplish this through the magento admin or does it require custom coding/extension? I'm on Magento ver. 2.1.7.

Answer 1

Unfortunately this would require custom coding or an extension. There is no way to do this in default Magento.
