I know someone who has tried Blue Apron, not exactly the same thing as you still have to prepare the food. She liked it, but thought it was kind of expensive. I guess that depends on where you live. going out to eat in Ohio is alot cheaper than NYC, so for us, not a cost savings, a higher cost place, it probably is.
I use a place called Dream dinners, but that is even farther away from delivery. It is a meal make ahead place (though I have them assemble the food for me.)
