A Shopify selling plan's price beside each class of discount

A selling plan can carry its own price: a pricing policy that takes a percentage off every delivery. A discount can then land on top of it. These carts put each class of discount on a line the plan has already priced.

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.

The plan's price is the line's price, not a discount

This plan's pricing policy takes 10% off. The cart reports that as the line's price and as a price adjustment on the selling plan allocation.

The same product has a 20% automatic discount set to one-time purchases. It did not reach the subscription line, and nothing in the cart mentions it.

An order discount's percentage is taken from the plan's price

A margin forecast for a subscriber with a code has to start from what the plan charges, not from the variant's price.

All three together

Each code allows the other two classes. The order of the arithmetic is the plan's price, then the product discount, then the order discount's percentage of what is left.

A subscription line and a one-time line in the same cart

A cart can hold both kinds of purchase. Here the tin is on its plan and the bag is bought once, with an app discount that prices the bag.

An order code set to one-time purchases is not refused on such a cart: it applies, and takes its percentage from the one-time line alone. On a cart with nothing but subscription lines, the same code is refused.

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 two 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. 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.

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.
