As a 'shielded' person I have been able to book slots as and when I need them, for which I am very grateful, as I can't get out to the shops. I am a smart pass holder. In my experience Ocado drivers are invariably cheerful and helpful. (I cannot, unfortunately, say the same for the other supermarket delivery drivers). On the rare occasion that I have needed to contact customer service they too have been helpful. The only reason I have not given 5 stars is that the M&S products are quite often on a short date and that fresh food, for example lemons, don't last as long as ones I used to get.
