I want to achieve the following:
When a users buys 3 products of the same category, then I want him to have the option to choose one more to buy for free – it should be from the same category as well.
How can I achieve that? Please tell me all the settings I have to make. Thanks
– Create a 100% discount coupon that is valid for that category.
– Set Minimum Quantity of matching products to: 4
– Set Usage Limits – Limit discount to: Every nth item
