A lot of people sell 'box' products, either as subscription boxes or one-offs. For example, I sell a bedroom decor box for students at unibedroombox.com.
I have 3 differently priced boxes and you get a different number of items in each box depending on the price.
It would be really cool if you could add a feature that lets customers select which specific products they want to go inside their box. Almost like 'products within the product', where the box itself is the product with a fixed price, and items in the catalogue are just the contents.
Thank you!
