For us, sit-down meals for two at a restaurant were usually at least $50 including tip.

I'm comparing Blue Apron specifically to a sit-down meal because for us the point of dining out was to relax and spend time together - something that cooking at least three meals a week together gets us to do. It also gets us to try ingredients we wouldn't normally consider.

That's just why it works for us, specifically! Definitely not for everybody. I don't work for them and the only stock I own is chicken stock. :)
