McCain Quick Chips 4x100g, both the Crinkle and Straight Cut versions, show £3.00 price for Morrisons. This is wrong: there is 2 for £4.00 multibuy online for these (order by 1/12/24), which is actually a cheaper price than the multibuy trolley.co.uk shows for Tesco. (The offer at Morrisons has been ongoing for a while, and hasn't ceased, and is still available on now checking today, is going into my checkout with £2 off the 2x£3 price, therefore this does not explain the absence of the multibuy on trolley.co.uk.) Thank you.
