"to prepare your menu selection arriving Tuesday, you will need: Soy Sauce, White Wine Vinegar,..." If you have 'em, fine, if not, you have a couple of days to stock up. That would eliminate the fairy's bottles of vinegar etc. (and lower costs?)."
That sounds like a really good idea. We also tried Hello Fresh, but indeed, many things we already owned in bigger bottles. Combine it with a lower price indeed and I wonder what it will mean for sales.
By the way, our local supermarkets are also starting to make these packages of "everything you need for one meal for 2 or 4". You can also have them delivered. In general though they are much more expensive then taking the products from the shelves, but that is to be expected. Robotozation of large stores combined with self-picking up of crates of supplies can fix that too (we have that at some stores, minus the robots).
Meanwhile here (in the Netherlands), you see more and more small electric vehicles delivering groceries around the city and picking up and bringing back elderly that want to shop.
Things are really changing.
