I'm fine having sorrel or scallops pre-packaged for me, but getting a triple-boxed egg or an onion wrapped in bubble tape just felt sad.
Oddly, the one thing they don't provide for you is cooking oil. Who are these high-income loners living in a bare apartment with just a single bottle of olive oil?
Just keep a dozen eggs in your fridge all the time.
To me the salient difference is between stuff I can easily pick up at the corner store (eggs, milk, flour) and things that it really is helpful to get in a kit box (premeasured hoisin sauce, blue potatoes, daikon radish).
The key is re-using the boxes, ice packs, and insulation liners, all of which we are setting up with our new delivery+return system for delivering a box and picking up a box each time we visit a customer.
