People may want the occasional experience of being a cook, without being super dedicated. It's like getting the occasional riding lesson, but never buying a horse. Horse enthusiasts say that caring for the horse, raising it, selecting a saddle, etc. is an integral part of the experience, and they might be right, but that doesn't stop places from succeeding at offering riding lessons.
I also like to cook, but I buy all my vegetables online anyway. I find the online experience good enough, and the convenience totally worth it. I would probably be an infrequent user of this service.
Would you be interested in a service where you could outline a meal plan for say, a week, and then get all the groceries required for those meals? I think the service would be more valuable as something that fusses the traditional on-line grocery shopping experience with this per-meal ingredients offering based off of recipes..
It would also be neat if you could allow people to store customized versions of recipes. Say they like more carrots in a particular soup, etc.
