Give away exact product combos — free bags, free shipping — without discount abuse. A code only works when the cart contains exactly what you configured. Nothing more, nothing less.
Open your Shopify admin to installThe app runs embedded in your Shopify admin.Define the precise items and quantities a cart must contain. Any extra item automatically invalidates the code — no stacking carts with freebies.
Make one delivery method — like USPS Ground — free when the combo matches, while every other method keeps its regular rate.
One use per customer, one-time purchases only, and no combining with other discounts — enforced by Shopify at checkout.
Pick a code, choose the products and quantities the cart must contain, set the discount percentage and the free-shipping method.
Send the code to customers in newsletters, package inserts, or social posts — it works like any Shopify discount code.
Shopify evaluates the cart at checkout. Matching carts get the discount and free shipping; anything else politely declines the code.
