I have used most of the major supermarket's online grocery shopping over the years, some were ok and some plain awful. I also used Ocado many years ago and it was comparable to the better of the rest. However, over the last 3 years or so I have returned to Ocado and am extremely impressed with how they have progressed. Hourly slots for delivery make it easier to plan your day, and their drivers will always ring ahead should they be early or late, I think I could say honestly that they have only been late once or twice. I hardly ever have a substitution and I have only been missing an item once and, again, they let me know beforehand by text and email. Their own brand goods are great value, their website is so easy to use and reminds you of items you may have forgotten. I have their shopping app on both my phone and iPad so even if I'm away from home, I can add items I may have forgotten. The Smartpass facility that I pay for annually allows virtually unlimited deliveries at no charge and saves me a lot of money, plus gives me offers on specific items. There are many more pluses I haven't mentioned but I can not think of a negative. Ocado is without doubt THE best online grocery store. I cannot recommend it highly enough and that is very unusual these days. Keep up the fantastic work.
