I think it's for people who are too lazy for grocery shopping but not lazy enough to just order takeout. That's a tiny sliver on the laziness scale IMHO.
Not quite. The meals I prepare from Blue Apron are significantly healthier than most takeout options - we control the sodium entirely and the majority of the ingredients are fresh vegetables and proteins. Plus the variety week to week is staggering - I've been getting weekly Blue Apron for more than a year and never had a repeated recipe. I've learned about all sorts of new foods I had never even heard of before. I am absolutely too lazy to meal plan and go grocery shopping, but ordering takeout isn't even a comparison point for me.
