"I think the ideal thing is the ability to click and say I want to make these four meals this week. It adds a list of perishables (meat, veggies, etc.) to my cart and a spits out a list of staples (spices, flour, soy sauce, etc.) for me to check to see if I have. Then I either have it delivered or it can print me out a shopping list. "

I would like that too. For this a "smart fridge" would actually make sense if it could check what you have already.
