Ocado online shopping is always reliable in terms of time keeping, the website is easy to use. The van drivers are polite and very pleasant characters. Ocado offers a very wide selection of products, well sourced and of high quality. I often take advantage of their special offers too. There are rarely any substitutions and I mostly get all the products I've ordered. I receive a message confirming my order, and a text on the day of delivery from the driver, giving his name, details of the van, all of which is very reassuring. Delivery charges are reasonable.
