Ocado was a blessing to me back in 2009 when I broke my ankle. It was so good having all my groceries delivered and the range of goods is amazing so I kept on using Ocado even once my ankle had healed. The website is extremely easy to use - much better than the Waitrose site. The time slot of one hour for deliveries is excellent.
The only reason I don't give 5 stars is the packers. Far too often I have had to claim a refund as whoever packed the goods did not take enough care when putting different items into bags. Last week the packer had put two 4 litre containers of milk on top of a pack of 4 peaches - of course the peaches escaped from their packaging and were squashed. I would still recommend Ocado despite this but it would be good if the packers had more training - it can't be good for the company to have to keep giving refunds due to poor packing.
It is so convenient that when I am on holiday I can arrange for a delivery to be made the day I return. I would not consider going back to doing my weekly shop in a Supermarket when I have the convenience of Ocado If I could give a score of four and a half I would, just get the packing right and it will definitely be a 5* rating.
