If you already have access to a kitchen, a decent set of cooking equipment (which you need regardless of whether you go for Blue Apron or not) is only a few hundred bucks, and the "basics" (pasta, rice, potatoes, onions, garlic, spices, veggie oil, olive oil, vinegar, flour, sugar, salt) are maybe 50 bucks more. Then, for less than a months' worth of meals from Blue Apron, you're set to start cooking for life.
My fiancee and I spend a grand total of 100 bucks a week, give or take, on groceries. This is in southern California, and usually including a cheap bottle of wine. We could spend even less if we wanted, but we're cooking some gourmet shit at home and constantly have leftovers, while generating 1/2 the trash of any of our neighbors thanks both to reusable containers for everything and composting. You can do SO MUCH better than Blue Apron, both in health and in environmental impact.
The same thing applies to Juicero: If I really want to start making fruit juice, I'll buy myself a decent juicer and get fresh, local fruit because it will always be cheaper than whatever they're sending out in their little pouches. I'd rather spend a couple hundred bucks on a quality machine (or better, just make smoothies since they're better for you and use the money I saved not buying a Juicero to buy a Vitamix) than buy into some cult hype bullshit.
