I cannot fathom why people would want to trouble themselves going to supermarkets. My chums tell me they want to see the selections - well there are plenty of pictures to see !! After all one does not have to spend time going to a supermarket - you just sit at your computer and like a fairy tale the goods arrive at your door delivered usually by a smashing helpful driver. The delivery is a one hour slot. I have been with Ocado since it started years ago and the experience is for the most part very good. The products are many and various and they introduce new things; there are reviews from customers which I use and have given some too.
Another and important thing for me is that I can do my shopping when it pleases me (in the middle of the night when I can't sleep if I want to) . I do not have to spend time on the road, carry heavy shopping or put up with the clamour in the shops.
