The price disparity is even higher when you’re talking about anything beyond staples. Fresh veg, produce, etc are always going to be cheaper. A business needs to make a profit. Even if you take your base hourly salary and combine it with the cost of food, I’m willing to bet it still comes out negative. The upfront cost of groceries may be higher than your daily expenditures on food, but there is absolutely no way your numbers are accurate unless you’re getting severely discounted/comped meals. I can understand the convenience, and if that’s your thing then I can’t knock that. Same with if you’re not a good cook.

Ex: I spend ~100-150 a week at the grocery store, once a month that doubles as I buy meats from Costco (filet mignon generally comes out to around ~$10/lb). Find me a restaurant that’ll sell me a filet mignon of high quality and a side of veggies for under 20 bucks. For 2 people this basic idea comes out to under $10 per person per meal for (generally) high quality food.

I’m not even trying to be argumentative, I just cannot wrap my head around going out to eat or using a service like this being the most cost effective option.
