Lyft/Uber could batch the deliveries, deliver within an hour specified by the customer... those companies already have data on ratings, they can pull the best drivers on-demand and offer premium pay that's still substantially less than the overhead of a store's truck + driver... plus offering last-mile logistics for multiple stores allows for greater efficiency over store-dedicated trucks. Insulated boxes, bags with ice, or have the stores define packaging... maybe the store packages goods separately in reusable cloth / insulated bags as appropriate for goods with a deposit for return (in-store or during the next delivery).
