Reliability: We've been using Ocado for about 7 years now on a weekly (sometimes more) basis. They are extremely reliable and have only been outside the 1 hour time slot on a handfull of occasions and have always let us know in advance and apologised on arrival. Produce: the produce is fresh, as described, and suitable substitions are offered when an item is out of stock. The range is vast allowing you to buy things from pet food to toys and cards (handy for last minite forgotten birthdays). Website: the website is one of the best we have used and is clearly much better than any rival provider. It is very easy to browse the produce or to search for a specific item. The website gives you details on shelf life and include ingredients and full product specification. Price: Ocado price competitively and also back up what they say with a price match promise which THEY will undertake and if there is any unfavourable discrepancy they will send you a money off voucher. In other words, you do not have to take them to task with any product that happens to be cheaper at their designated rival as they will do it themselves and volunteer the money off. Customer service: the customer service is excellent and they are very customer focused. On the rare occasions we have had complaints, they have been resolved incredibly speedily and always to our satisfaction. Overall: All in all it is a first class service and considerably better than any rival provider. I give it 5/5.
