# Set up a Complete the bundle offer

> Pair the current product with set products so shoppers buy the complete set at a discount.

**Complete the bundle** pairs the current product with products you pick, such as a shampoo with its conditioner. It's a Mix and match offer with a set companion. Shoppers buy the whole set at the prices you choose.

**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 offer

1. In Shopify admin, open **Apps** → **Section Store** → **Bundles**.
2. Click **Add bundle**, then **Build your own**, then **Choose** on **Complete the bundle**. The bundle starts with a **Single** offer at full price and a **Complete the bundle** offer. On an existing bundle, click **Add offer**, then **Complete the bundle**. That offer is called "Complete the set". Both start at 10% off each item.
3. Open the offer. It's called **Complete the bundle** from the preset, and "Complete the set" when you add it.
4. Open **Item 2** and click **Select products and variants**.
5. Pick the companion product and its variants, then confirm.
6. Set **Quantity** and **Price** on each item.
7. Click **Add item** to add more products to the set.
8. 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.
9. Click **Select products** or **Select collections**, then pick the items and confirm.
10. Click **Publish**, or **Save** on a live bundle.

## How it works

- One companion: the row shows that product and shoppers can't swap it.
- Several companions in one item: the first available one fills the row, and shoppers can swap it with the picker.
- Turn on **Require customers to choose a product** to start the row empty.
- Everything else works like Mix and match. The discount applies only while the whole set is in the cart.

## If it doesn't work

- "Add a companion product to publish": the item has no product. Click **Add companion product** and pick one.
- The companion row says **Product unavailable**: no product in that item's list can be sold. Add products that are in stock. See [Why are products missing from the Mix & Match picker?](https://section-store.orka.help/a/products-missing-from-the-mix-and-match-picker)
