I have been an Ocado customer for about 9 years now. I had tried Sainsburys, Asda, Morrisons and Waitrose prior to trying Ocado. I have never looked back! I receive 2-3 deliveries a week, I would say they are on time at least 98% of the time. The drivers are almost always (on rare occasions a miserable one shows up!) friendly and helpful. I love the bagging method of colour coding your freezer, fridge and cupboard goods, makes it a cinch when you are in a hurry, to get the cold/frozen goodies stored. I love the huge range of products (including non perishable and retail items - excellent for forgotten gifts or when you are short of time) The delivery time slots give plenty of choice (especially if you prefer organic and fresh as we do) I have never experienced a problem with refunds and find the customer service to be helpful, polite and prompt in sorting out any issues. My life is made soooo much easier through Ocado!
