I've just 'braved' the supermarkets... tried Sainsbury's at Mere Green... resembled Glastonbury car park in the rain. Sacked that off and went to M&S Food Hall nearby... busy but manageable and the self service checkouts were moving quickly as the majority of the customers were elderly and wanted a traditional checkout (glaring stereotype I know!).
My own fault, partly, leaving it this late (but I have been ill and not well enough to go out).
