800g boxes of Coco Pops are on offer @ £2 at the Co-op. They are the special 550g packs with 45% extra free. B.B. date of 6.11.14. Same packs are £3 in Sainsbury's.
And yes, I know they are full of sugar - but I buy them occasionally as a treat for my teenagers (but only if on offer!).
Also, the Co-op seems to be discontinuing a number of lines at the moment - picked up various items incl. Finish dishwasher tablets, Lenor fabric conditioner and bottles of wine marked down to 25% of original prices. Could be worth a look in your local Co-op store.
