Found 10th Dec 2011
Just back from Asda High Wycombe where a roll of 8m x 0.45m brown paper, marked down at £1.20, scanned at 2p! So I went back and bought another 4 (from the self-scan tills). HUKDers have confirmed it works nationally and you can all save ££s from sending your Christmas pressies! Receipt in first post. Merry Christmas everyone!
