Ocado is excellent for fresh foods, wisely sourced. Its own range of products is very good too. My only gripe is that it is not as good on some ethnic foods - notably Indian and Middle Eastern/Arab/Turkish foods - as Sainsbury's and Morrison's. Egyptian 'ful' beans, tinned cooked aubergines (imam bayildi), the tastiest falafel, are not to be found there, despite its good range of e.g. Chinese foods.
