I actually ordered a box recently, since they gave out 50% off vouchers for the first week .
It was basically just some stuff you'd buy at Woolies and a recipe. Fine at 50% off but over priced and too much work to cook the recipes at full price. Cancelled after first delivery.
Maybe they'll see a short term boost but surely home delivery of cheap staples and things they actually want to cook will be what people move towards if this stretches beyond a month.
