Every nth item. n = min qty
n is the ‘minimum quantity of matching products’ on the ‘usage restrictions tab. For example, if n = 3, every 3rd item in the cart will be free (buy 3, pay 2). The products are sorted expensive to cheap before applying the discount, and then every nth item will be discounted.
n Lowest priced products
– Similar as above, but the n cheapest items in the cart will be discounted.
