This better than price-matches Ocado's Buy 2 for 80p deal which is next cheapest so has to be a good offer, especially from the Co-Op!
This was found in a bargain basket in my local Co-Op, tastes REALLY good and feels like a bargain to me. Not sure if this is nationwide.
To make soup: Empty soup into a saucepan. Gradually add one can of water (or half milk and half water for extra richness) stirring constantly. Heat the soup to serving temperature. Do not boil or overheat as this impairs the quality.
To microwave 650W: Pour contents into a microwave dish and stir in one can of water (or half milk and half water for extra richness). Microwave for 5 minutes on high power, stirring after 2½ minutes..
