Yes..... 500g packs of these are marked down as 50p in Crayford and pepper hill stores.
States "SALE reduced from £4.02, then £3 now 50p...While stock lasts" DU is Sept/Oct 2017
Bought 10 of these for a fiver!! loads still left on shelf.
Worth having a look at your local.
Seems like they are clearing this line, as its not available online now.
Good Luck & Merry Christmas
