Ocado are far and away better than any other home shopping service that I've used from any of the big names. Their drivers are friendly and very helpful, and will even carry your shopping to your fridge for you if you want them to. Compare that to Sainsbury's drivers who expect you to stopp to pick the bags out of the packing boxes while they stand and wait. They price match with Tesco, they refund you the cost of carrier bags when returned, deal with issues and returns effectively, and have a great range with worthwhile offers that make sense to the customer - and if they're unable to supply all components of an offer, they will still apply the offer to the remaining parts of it, unlike every other service provider I've used.
