Areas that are particularly outstanding include: (1) Delivery slot availability (2) Time accuracy of the delivery, especially meeting the small 1 hour window (unlike the 2hr slots of some other supermarkets) (3) the Ocado iPhone and iPad apps; simple, fast and visually appealing layout (4) SMS informing of delivery details to provide security reassurance (5) SMS providing notice of any missing or substituted items (unlike other supermarkets annoyingly I've used) (6) Excellent product quality/choice; the last skinless and boneless cod fillet were exceptionally fresh and after cooking en papillote were exquisitely tender and moist. (7) Courteous delivery drivers
