Selling option bundles are basic upsell / cross sell and need a bit more work to come up to competitor app standards. Being free the basic sell features are ok and the configurable colours and text is pretty good. The app suffers from inability to BOGOF, inability to include a free item into a bundle, or be able to discount more if customers buy more. Sadly other apps provide these features. The side pop-up needs refinement performance wise as it causes a noticeable slow down on the page. Overall a good app but needs more given it has moved to a subscription model.
