This one might seem like a minor shift for the consumer experience, but a key difference with other services is that it's actually a sustainable business model. Because they do batched deliveries with hub-and-spoke distribution, the cost for deliveries is lower, so they'll have way higher profit margins than something like Postmates. Uber eats will be able to hold out since profits realistically don't matter to them, but I think the main stronghold something like Bento Club could have is the fact that the current courier model doesn't really work in the long-run.
