I'm looking for ways to implement an e-commerce for an organic farmer who sells their products, he offers products and product bundles. Every product bundles has its own price. Each bundle are predefined products group. But I want that when the user buys, can unchoose at most, two products of the bundle and change them for another product in a predefined group of products.
I wonder if anyone knows how I can work this way the product bundles. I've been searching, I saw Tech Talk about commerce bundles, I tried commerce_bundle... but I can't find anything to do this.
Any idea or clue is welcome!
