Went to Tesco's in Thetford this afternoon and was looking at sun cream when I spotted travel adaptors hanging reduced to 49p. Went to the till and it scanned through at 1p!
Not sure if it's nationwide! Be ware though as there was two hanging there (they look pretty similar and do the same thing everything on the label was exactly the same except the barcode) both labelled at 49p but one of them scanned at £1.93.
Sorry if I've done any thing wrong!
