Shopify now offers native support for product bundles
Increase your average order value with Shopify’s new bundles offering, which includes a number of options depending on your bundle use case. All options integrate seamlessly into the admin and include real-time inventory syncing.
To create fixed bundles and multipacks, you can use our free new app, Shopify Bundles.
For support for mix-and-match bundles, you can download one of these updated bundle apps from the Shopify App Store or, if you’re a Shopify Plus merchant, you can build your own custom bundle offering using our APIs.
