I wish this video was longer and went into more detail, although I guess Ocado like to keep things light as they make money on selling this tech to other supermarket chains. I used to be an Ocado customer for about 9 years or so and they were very, very reliable in terms of deliveries and order fulfillment (I rarely ever got substitutes) - I'm wondering if this tech and other things in the warehouse played a huge role in making sure inventory/supply always met demand. When doing a similar online shop with ASDA we get substitutes/missing items/unavailable items every week, and the vans are always late.
