54 Peppermint Mentos Sugarfree Gum at Burnley Poundland. These are tubs marked at 20% extra free so can't see it being available on a regular basis and maybe not at all Poundlands.
Not as nice as Wrigley's Extra but still does the trick. The difference in price sweetens it up for me. Ha.
I like these types of tubs for the car. Very handy
