Automatically fulfill bundle SKUs
Automatically mark your bundle SKU as fulfilled so that it does not get sent to your fulfillment centre.
To automatically fulfill your bundle SKU, go to your Preferences, and scroll to the Fulfillment section. Enable auto-fulfillment by checking Enable automatic fulfillment of bundle SKUs.
Once your customer adds a product to cart, they would see the bundle product, but not its individual bundled SKUs.
