Please can you let me know the best way to set up a buy 1 get 1 free on a product? When they purchase 1 Supreme Squash Racket they will receive 1 Supreme Squash Racket free of charge (free product is the same as the one they purchased).
The offer will always available for the Supreme Squash Racket and if possible I would like the free Supreme Racket to be aded to the cart automatically when they purchase 1 item, so they don't have to add 2 items to the cart to get the offer. Also if the customer added 2 Supreme rackets to the cart they would get 2 free Supreme rackets, and the same for 3 rackets, 4 rackets etc.
Setting up the product in Magento Community Edition ver. 2.1.0
Any help would be much appreciated.
Maybe this links will help you. Those are for M1 but the idea is the same:
Let us know if you were able to create the rule.
Here's another one for Magento2:
In case you need a ready solution that adds a promo product to cart automatically, you can try this module - Free Gift for Magento 2.
There is also an option to display promo banners to inform your customers about the promotion.
