i.am.gretchen review for Shopify Bundles

I don't see how this is different from just creating a product that is the stuff I wanted in the bundle. I must have misunderstood the other reviews. I thought it added each product to the cart then customers could add or delete them if the bundle wasn't exactly what they wanted (or if they wanted a different variant). This collection has a discount with a minimum quantity. It isn't discounting, either. It doesn't pull over photos or descriptions. I really don't get why anyone would use this. Just make a product that is the bundle.
