Mysupermarket is a free shopping and comparison website for supermarket shoppers that includes direct links with the big four UK supermarket chains.
Each product also shows the weight or volume, price, special offers and price per unit, as well as detailed nutritional information.
Once you get to the checkout the site’s Trolley Checker tool displays the cost of purchasing those contents at each of the 4 online stores. In addition a Price Checker tool recommends changes to save you money. There is also a Health Checker tool to help remind you of healthier product options.
mySupermarket definitely provides a valuable service which puts it in good place to be a kind of Supermarket Concierge.
As a suggestion, I think it would be nice to see them add Ratings / Reviews of delivery services.
