My ex wife and I shopped at Asda for 20 + years. She always said that Tesco were more expensive. And she was right. And whenever I am on the UK mainland I load up my car at Asda before I get the ferry back to the IOM. As there is no Asda here so no choice. In fact the best place here is Tesco, ironically......as it is better than the local supermarket chain.
