Just came across this, hard to spot as it was not promoted as being on offer, however the price was printed on the box as a part of the packaging - £1.42. Tesco Price is £2.69
This is a new product from Kellogs and I tried it when it was slightly reduced at Tescos a couple of weeks back - they are delicious! but will not pay the asking RRP, too expensive for a bowl of cereal.
However I believe this is a good deal, but I have no doubt that you'll be the judge of that.
It is the cheapest i have seen these so far.
May benefit you if you like these and have a costcutter nearby.
