# Set up quantity breaks (buy more, save more)

> Give a bigger discount at each quantity of one product, like buy 2 save 15% and buy 3 save 25%.

Quantity breaks give a bigger discount at each quantity of one product. Add one **Volume discount** offer per tier, such as buy 2 save 15% and buy 3 save 25%. At checkout, the biggest tier the cart reaches wins.

**Set the Products rule before you publish.** A new bundle starts on **All products**. Without that step, the deal applies to every product in your store.

## Set up the tiers

1. In Shopify admin, open **Apps** → **Section Store** → **Bundles**.
2. Click **Add bundle**, then **Build your own**, then **Choose** on **Quantity breaks for the same product**. The bundle starts with two offers: **Single** at full price and **Duo** at 15% off.
3. Under **Offers**, set **Quantity** on each offer. It's how many units the offer adds to the cart.
4. Set **Price** on each offer:
   - **Full price**: no discount.
   - **Percentage off**: enter the percent in **Discount per item**.
   - **Amount off**: enter the amount per unit in **Discount per item**.
   - **Fixed price**: enter the price of the whole offer in **Total price**. For 2 for $30, set **Quantity** to 2 and **Total price** to 30.
5. Click **Add offer**, then **Volume discount**, for each extra tier.
6. Change each offer's **Title** and **Subtitle** in its card.
7. Under **Products**, pick **Selected products** or **Selected collections**. **All products** is the default for a new bundle. Without this step, the deal applies to every product in your store. Keep **All products** only if you want that.
8. Click **Select products** or **Select collections**, then pick the items and confirm.
9. Click **Publish**, or **Save** on a bundle that's already live.

Shoppers see one row or tile per offer, with the price and any struck price. They pick one and click Add to cart. The widget adds the right number of units.

## How the discount works at checkout

- The biggest tier the cart reaches wins. With **Percentage off** or **Amount off**, that tier covers every unit of the product. With tiers at 2 (15%) and 3 (25%), 5 units get 25% off all 5.
- **Fixed price** works in packs. With 2 for $30 and 5 units, two packs cost $30 each. The fifth unit falls to the next lower tier that fits.
- A **Full price** offer with no gift gives no discount.
- Units of one product count together across its variants. A blue and a red shirt make 2 units.
- Different products never add up. For "any 3 products", use [Mix and match](https://section-store.orka.help/a/119-how-to-set-up-mix-match-bundle-deals).

## If it doesn't work

- Shoppers want to type a quantity: add a [Quantity selector](https://section-store.orka.help/a/128-add-a-quantity-selector-to-bundle-offers).
