Colgate Total Advanced Toothpaste 125ml, on promotion at £2.00 each at Morrisons. Cashback through ClickSnap (part of Quidco), buy 2 get £3.00 cashback, hence, works out at 50p each tube. You will need to hurry as the ClickSnap cashback for this ends on Tuesday 8th August 2017. Looks like a cross over promotion.
