Bundleup lets you create bundles without the need to edit your theme. You can add options and create multiple bundle versions all from your current admin. The app recalculates inventory of bundles based on component stock levels so you don't oversell. After a bundle sells you can choose to automatically edit the order into the bundle component products.
