I'd even pay for a service that would let me pick, say on Sunday, what to eat for the rest of the week (guided by good suggestion algos of course) and would then deliver the groceries for that in one or more deliveries over the week. But even without paying for that service, it would let a supermarket get near 100% of a certain customer's total spending on groceries.
