# A Shopify automatic discount beside an app's automatic discount

A store can run Shopify's own automatic discounts and automatic discounts an app's function decides. A buyer's cart can meet both. These carts put one of each in the same cart, on separate lines.

Verified 3 November 2026 on Shopify’s 2026-10 API, in carts built on a real store. Each statement marked with a tick is checked against the cart Shopify returned.

## In the cart, Shopify's automatic discount reads like an app's

The first cart holds a product with one of Shopify's own automatic discounts, a plain 20% off with no app behind it. The second is an app discount whose function prices a different product.

Both come back the same way: an automatic discount allocation on the line, carrying the discount's title. The cart does not say which kind of discount made it.

#### Into the cart

- 1 × Travel Tin at $50.00, bought once

Each discount is set to combine with product discounts, and each prices its own product.

Two product discounts on one line do not stack. On two lines, with both allowing product discounts, each line got its own.

## An automatic discount that combines with nothing was dropped, without a warning

This store has a second automatic discount of Shopify's, $4.00 off another product, set to combine with nothing. Alone in a cart, it applies.

Beside the app's discount it did not, though the two were on different lines and the line it prices had no other discount. An automatic discount is not in the cart's list of codes, so there was no flag and no warning: the line was simply at full price.

## The same happened between two of Shopify's own

No app is involved in this cart. The 20% discount and the $4.00 discount are both Shopify's own, on two products, and the second combines with nothing.

In this cart the discount that stayed was the larger one.

## An order code beside each of them

The order code combines with product discounts. Beside the automatic discount that allows order discounts, both applied. Beside the one that combines with nothing, the code was refused, and this time the cart said so: a code has a flag and a warning, an automatic discount has neither.

## How this was verified

Every cart on this page was built through the Storefront API on a Shopify Plus development store we keep for this, on API version 2026-10, and read back as Shopify priced it. The store sells three products in these carts: Single Bag, at $40.00, also sold on a selling plan named “Every 30 days” that has no pricing policy; Travel Tin, at $50.00, also sold on a selling plan named “Every 30 days, 10% off” whose pricing policy takes 10% off; Brew Scoop, at $20.00. It quotes two delivery rates to a US address.

It has one automatic app discount, titled “Offer Suite”, with a product class and a shipping class, set to combine with product, order and shipping discounts. Its function reads a cart attribute: with it, the function takes 25% off one unit of Single Bag bought once, or $8.00 off the unit on its selling plan, and makes the cheapest delivery rate free. Without it, the function returns no operations.

The other discounts in these carts, as they are set on the store

| Discount | Class | Gives | Combination setting |
| --- | --- | --- | --- |
| Automatic, “VERIFY tin 20% off” | Product | 20% off the tin, one-time purchases only | combines with product, order and shipping discounts |
| Automatic, “VERIFY scoop $4 off” | Product | $4.00 off the scoop, one-time purchases only | combines with nothing |
| Code VERIFY-ORDER10 | Order | 10% off the order, one-time purchases only | combines with product and shipping discounts |

A suite builds these carts again and reads the discount settings from the store before it does. A statement that no longer matches the cart takes this page down until it is corrected, and no cart stands for more than 90 days without being built again. This is what one store returned on one API version: your store’s plan, markets and other apps can change the result, so build the cart.
