Shopify’s own discount codes each hold one kind of discount, so 20% off plus free shipping normally takes two separate discounts. With OneCode: Stackable Discounts, one code holds both: a 20% product discount and a free shipping discount. The customer enters the code once and gets both. If you want, shipping can be free only above a minimum spend while the 20% applies to every order.

What the customer gets

In this example the code is BFCM20, and shipping is free from $50.

  • An $80 cart (a $50 shirt and a $30 tote) gets $16 off the items and free shipping. The customer pays $64.
  • A $40 cart gets $8 off the items and pays $8 for shipping. The customer pays $40.

An $80 cart with BFCM20: the $50 shirt is $40, the $30 tote is $24, shipping is free instead of $8, and the total is $64

A $40 cart with BFCM20: the $40 shirt is $32, shipping is $8, and the total is $40

The $50 minimum is checked before the 20% comes off. A $60 cart still gets free shipping, even though the items cost $48 after the discount.

At checkout, the discounted items are labeled with the code, and shipping shows as free.

Set it up

  1. In OneCode, click Create discount, choose Discount code and enter BFCM20. If you’d rather apply the offer without a code, choose Automatic discount and give it a Title.
  2. Click Add Discount Type. A new type starts as a Product Discount with Percentage and All Products. Enter 20 in Percentage.
  3. Click Add Discount Type again. Set Discount Type to Shipping Discount and keep Free Shipping.
  4. To make shipping free only from $50, go to the shipping discount’s Per-Discount Conditions and click Add Condition. Set Field to Cart Subtotal, Operator to Greater than or equal to and Value to 50. Skip this step if shipping should be free on every order that uses the code.
  5. If the offer has a deadline, set the start and end under Active Dates.
  6. Click Save discount.

Here is the same two-part setup in the editor on another code, SUMMER25. Its 20% is limited to one collection, and its shipping is free on every order:

OneCode editor for code SUMMER25 with two discount types: a 20% Product Discount on the Summer Collection, and a Free Shipping discount on all rates

Options

  • 20% off one collection only: set the product discount’s Target to Specific Collections and pick the collection.
  • Only the cheapest shipping rate free: set the shipping discount’s Rate Selection to Cheapest Rate. It makes the cheapest paid rate free and leaves the other rates at full price.
  • Both parts only from $100: put the minimum on the whole code instead. See spend $100, get 20% off and free shipping.

The 20% and the free shipping are parts of one discount, so they always apply together. The Combinations card only matters for other, separate discounts a customer might use at the same time.

You can put more on the same code, such as a fixed amount off the order. See product, order and shipping discounts in one code.
