BundleFlow: Bundle Builder

BundleFlow lets merchants sell bundles that shoppers assemble themselves. Customers pick their components on the product page, and the app expands the bundle into its individual products in the cart, validates it at checkout, and applies the right price. Any bundle can also be sold as a recurring subscription that customers skip, pause, edit, or cancel from their account. Merchants can attach a free gift to an offer and see how bundles and subscriptions perform. No theme code editing is needed.
