With OneCode: Stackable Discounts, you can make a gift product free once the customer spends a minimum, and give free shipping on the same discount. The customer adds the gift to their cart, and the discount takes it to $0 at checkout. OneCode doesn’t add the gift to the cart, so tell customers about it on your product pages, cart or announcement bar.
Example
A $20 tote is free, and shipping is free, when the customer spends $100 on other products.
- $110 of products plus the tote ($130 cart): the tote is free and shipping is free. The customer pays $110.
- $110 of products without the tote: shipping is free.
- $90 of products plus the tote ($110 cart): shipping is free, but the tote is full price, because the cart is under $120.


Set it up
- In OneCode, click Create discount and choose Automatic discount. Enter a Title such as
Free tote and shipping over $100. Customers see the title next to the free gift. Choose Discount code instead if customers should type a code. - Click Add Discount Type. Leave it as a Product Discount, and enter
100in Percentage. Set Target to Specific Products and pick the tote. - Click Add quantity limit and enter
1in Quantity Limit. - Under that discount type’s Per-Discount Conditions, click Add Condition. Set Field to Cart Subtotal, Operator to Greater than or equal to and Value to
120. - Click Add Discount Type, set Discount Type to Shipping Discount and keep Free Shipping. Add the condition Cart Subtotal Greater than or equal to
100. - Click Save discount.
Why the gift needs $120, not $100
Cart Subtotal includes the gift’s own price. With a threshold of $100, a customer could spend $80 and add the $20 tote to reach $100. Setting the threshold to your minimum plus the gift’s price keeps the minimum at $100 of other products. Free shipping stays at $100, so customers who don’t add the tote still get it.
Good to know
- If a customer adds two totes, one is free and the other is full price.
- If the same discount also gives 10% off all products, the tote still gets 100% off. Each item gets the product discount that saves the most.
- The gift must be a product customers can add to their cart in your online store.
Choose one of several gifts
Under Specific Products, pick every gift product. The quantity limit of 1 makes only one of them free, the cheapest one by default. Set the Cart Subtotal threshold using the most expensive gift’s price, so no gift can push the cart over the minimum.
A gift when they buy a specific product
Instead of a Cart Subtotal condition, add a Global Condition: Product In Cart, Contains, and pick the product they need to buy. The gift is then free whenever that product is in the cart. A Global Condition applies to the whole discount, so the free shipping also needs that product in the cart. See buy this, get that.
Shopify’s own Buy X Get Y discount only discounts the item the customer gets, so free shipping would be a separate discount. With OneCode, the gift and the free shipping are one discount.
