How to Create an “Nth Item Discount” Campaign

Create promotions like “Every 2nd item is 50% off” or “Every 3rd item is $10 off”. The Nth item in the cart gets a discount.

Prerequisites #

Savings: $100 (25% off total)

Example 2: “Every 3rd Item $20 Off” (Fixed Amount) #

Settings: N=3, Discount Type=Amount, Value=20

Customer buys 6 T-Shirts ($40 each):

Savings: $40 (17% off total)
