I highly recommend checking out PickyStory’s combo products.
Combo Products enable you to bundle products as a single product, add to collections and advertise across your marketing channels. Aggregate several products as a pack/gift box and sell them through a dedicated product page as one product.
Hi @NatureBed , our app Simple Bundles does exactly what you’re looking for. Bundles appear as a single product at checkout and then Simple Bundles edits the order and adds the bundle contents after it’s been created. Then, the inventory for the individual SKUs is adjusted and the bundle quantity is also adjusted based on what’s available so you never oversell.
Here’s a bundle example similar to yours. As shown in your mock, you can also repeat the same products in your bundle for your customers to select from. You can also create as many bundle combinations as you’d like with our infinite options bundle type.
Hope this is helpful and please let me know if I can help out with the setup!
