I've been using BA for a while with my family (wife and son). We love it. We still buy a meal or two for the weekend at the grocery store (or Prime Now), along with the other household staples, but the meal planning is much easier now, and we really like how much less food we end up throwing away (e.g. unused produce). The other "waste" that is non-recyclable is negligible (little squirt packets of liquid), everything else is recyclable--boxes, ice packs, liquid bottles, veggie bags, etc.

The only thing we wish it had is support for dietary restrictions--my wife has celiac's and we have to work around that sometimes.
