# Volume discount

> Buy more, save more — tiered quantity discounts

Volume discount shows a "buy more, save more" widget on the product page: customers pick a quantity tier (Single, Duo, Trio, and so on), and each tier unlocks a bigger discount. It's the most flexible offer type — it also supports Buy X Get Y Free and free-gift incentives.

## How tiers work

Each offer has one or more tiers. For every tier you set:

* **Title and subtitle** — for example "Duo" / "You save 30%"
* **Quantity** — how many units this tier requires
* **Discount type** — `Default` (no discount, used for a baseline tier like "Single"), `Percentage`, or `Fixed amount`
* **Discount label and badge** — the text shown on the tier, and an optional badge like "Most Popular"

Customers select a tier, and the price updates live to reflect the discount for that quantity.

### Buy X Get Y Free

Instead of a percentage or fixed discount, a tier can be configured as **Buy X, Get Y Free** — the customer pays for X units and receives Y additional units at no cost. This is useful for offers like "Buy 2, Get 1 Free" without needing to calculate an equivalent percentage discount.

### Free gift add-ons

Any tier can include one or more **free gifts**: a specific product (and variant) that's automatically added to the cart at no charge when a customer selects that tier. This is a good way to make a higher tier more attractive without discounting your core product further.

## Where the offer applies

Set **visibility** to control which products show the offer:

* **All products** — shows on every product page
* **Specific products** — pick individual products
* **Specific collections** — shows on every product inside the collections you choose

### Combined volume discount

By default, the quantity tiers only count units of the *same* product/variant. Turning on **Combine with other products** lets the tiers count units across a set of related products (and optionally collections) toward the same discount — useful when you want customers to mix and match products but still unlock the volume discount, rather than requiring three of the exact same item.

## Urgency and layout

* **Countdown timer** — add a countdown with a custom title and description to create urgency. When it's enabled, it appears above the tier list.
* **Template** — display tiers **vertically** (stacked list, the most common layout) or **horizontally** (side-by-side cards).
* **Header and footer text** — customize the heading above the tiers (for example "Buy More, Save More") and the footer note (for example "Free Delivery").

## Design

Colors, fonts, borders, corner radius, and badge style are all configurable — see [Design customization](/design-customization) for details that apply across every offer type.
