How to create a Product Bundle using Crate Bundles in Shopify
To create a bundle, click “Manage” under Bundles from the Dashboard
Next, click “New Bundle”
Configure your Bundle. Provide it with an internal name that won’t be visible to your customers. This is great for managing your bundles. You can provide it with a custom Frontend title or leave it as is. You can also add a percentage discount to the bundle. This will discount all items in the cart when added together.
Next, select a lead product. This is the product where the bundles will show. A bundle will always contain the lead product of course.
Finally, select up to 3 products you wish to bundle the product with. You must select at least 1 additional product.
Once done, hit the save button. You bundle should now be visible frontend.
