# Discount Center: Buy X for Y

Buy X for Y is the discount type behind "3 for 2" deals and similar offers. The customer buys a set number of products, and the cheapest one (or more) is free or discounted. The store applies it automatically — there's no code.

This type is only available if Buy X for Y is enabled for your store. If you don't see it as an option, contact support to have it turned on.

## How the rule works

A Buy X for Y discount has one rule, made of two parts:

-   **Number of products to trigger** — how many qualifying items the customer needs in the cart (the "X").

-   **Discount** — what they get on the cheapest item(s) once they hit that number.

The discount can be one of three kinds:

| Discount kind | What the number means | Example |
| --- | --- | --- |
| **Cheapest free** | How many of the cheapest items become free | Trigger 3, value 1 → "3 for 2" (1 of every 3 free) |
| **Percent** | Percentage off the cheapest item | Trigger 3, value 75 → 75% off the cheapest of every 3 |
| **Fixed amount (kr)** | Kroner off the cheapest item | Trigger 3, value 50 → 50 kr off the cheapest of every 3 |

The discount always lands on the **cheapest** qualifying item in the cart. That's what makes "3 for 2" work — the customer pays for the two most expensive and gets the least expensive free.

## Setting up the rule

-   On the discount's detail page, find the **X for Y rule** card and click **Edit rule**.

-   Set **Number of products to trigger**.

-   Choose the discount kind (Cheapest free, Percent, or Fixed amount) and enter the value.

-   Write a **Description** — this is shown to the customer in the cart as the discount line label, so write it the way you want them to read it (for example "3 for 2 on socks").

-   Save.

As you edit, a live **Customer sees** preview shows how the deal reads — for example "Buy 3, cheapest item free". Use it to sanity-check the rule before saving.

## What it applies to

A Buy X for Y discount targets products the same way the other types do — all products, specific products, a category, or manufacturers.

Unlike quantity discounts, Buy X for Y has no per-tier price columns on its product list. The discount lands on the cheapest item in the qualifying cart, so there's no fixed per-product price to show.

## Tips

-   For a classic "3 for 2", use **Cheapest free** with a trigger of 3 and a value of 1.

-   For "buy 2, get the cheaper one half price", use **Percent** with a trigger of 2 and a value of 50.

-   Write the cart description clearly — it's the only text the customer sees explaining why their total dropped.
