Service is mostly reliable and dependable. What is most irritating is when a product simply disappears from sale without warning and there is almost denial that it was ever on sale. Drivers vary from very helpful - most of them but there are a few you would rather not see again. The delivery pass is expensive especially now that Waitrose deliver most of the same goods free for a minimum spend. I've never used another supermarket delivery service so I can't say whether Ocado are better or worse than average.
