You may notice that the bundle appears in your Orders as a single product, with all of the individual products that make up the bundle appearing as line item properties.
This is because Bundable is a single SKU bundling app.
This is where a single product is generated by the app and appears in the carts, emails, Orders sections of your store as a single product. The products that make up each bundle are listed as line item properties.
This is great for merchants who:
Want to have a unique SKU for their bundle product
Are fulfilling their own orders and not using any 3rd party fulfilment apps
