Ocado are excellent, I have been using them for getting on for ten years. I have only had substitutions on about two occasions, if there is ever any damage (rare) to any goods there is an immediate refund, the frequent delivery slots are very useful and my shopping has always been delivered on time apart from a very few occasions when the driver has rung to say what is happening and when he will arrive. I frequently recommend Ocado to friends. I hope that you will not stop delivering Waitrose goods. Rumour has it that Morrisons will replace Waitrose. I would probably then transfer my allegiance to Waitrose Deliver.
