Improved bundle functionality
There should be an ability to create bundles by combining any product, addon, or service in any combination and number. I should be able to combine two addons in a single bundle, or three addons and one service, for ex.
Each bundle should have its own name displayed on a shopping cart product list, and it should list all the components thereof, with individual prices and quantities for each component shown underneath the bundle name. There should be a total cost for the bundle and a display of savings compared to the total original price of all bundle components.
This is an extremely important marketing function, and most sellers should welcome this feature, as the current implementation of the bundle functionality is fragmented at best.
