My gf and I live in SF and use Sprig which is healthy and around $12-15/person including delivery. Its cheaper than when we bought groceries and cooked (which we didn't enjoy) because we had to rent a Zipcar to go to the grocery store, pay SF food prices and ended up wasting a lot that we didn't eat. We didnt waste out of poor planning but unpredictable schedules. She has sudden client meetings come up in the evening or I have to unexpectedly travel down to a different office in the south bay.

Considering my company provides breakfast and lunch, the high price for dinner isn't that bad. Also on weekends we're usually not home to cook, which increased the probability of wasting groceries we didn't eat during the week.

As millennials without children and good jobs who don't enjoy cooking, there isn't any reason to spend the time planning meals, renting a car and going to the grocery store on the weekend when I'd rather be doing anything else. If I lived in a smaller city, where I had a house and a car without an app that delivered healthy food, then it would have to change, but thats a boring life.
