About product bundles
The Product bundles feature allows you to sell several products to your customers in one package. Bundles are helpful, for example, if you want to create a special offer on specific products or sell all the compatible products simultaneously.
How to add a product bundle
Go to Products > Product bundles.
Click Add a product bundle.
Fill in the details and attach products from the Product bundle contents section.
The details of a product bundle are pretty much the same as they are in other products. The only difference is that a product bundle consists of other products.
Attaching products to a bundle
You can attach products to a bundle in the Product bundle contents section by using the search function. If the product has options (size/color), you can choose it upfront or let the customer choose it.
After you have attached the product to the bundle, it will appear under the search bar. Next, you can set the stock amount into the Amount field on the right side of the page (how many units of that product are included in the bundle).
Product bundle's stock amount
A product bundle doesn't have a stock amount of its own. It follows the stock amounts of the products included in the bundle. If one of the included products is out of stock, the bundle cannot be purchased (unless you have allowed it in the Inventory settings).
How the bundle is shown in the online store
Like any other product, customers can find product bundles in the product groups they are attached to. You can also create a separate product group for bundle products if you want to. Then your customers might have a better chance of finding bundles.
You can also link together the product bundle, and the products included. The online store usually shows the related products at the bottom of the product page.
