Selling products exclusively through bundles on Simple Bundles v1.0
Follow the steps below if you want to make products available only through a bundle.
After you have added an "active" product in Shopify to a bundle in the Simple Bundles app, go to the product settings page in Shopify, by clicking on the product link under Products.
Click on Status and set the product as Draft.
You can leave the Online Store channel enabled as this will ensure correct performance when the bundle is added to the cart.
