It is always worth taking a calculator (there's usually one on your mobile/cell phone) and double checking prices AND weights. For example: Limpit likes those 'Fridge Raiders' chicken bites. They come in individual packets and in a packet of 3. Last week in Sainsbury's, 3 individual packets came in at 6p less than a packet of 3, because the 3pack had 100g less in it. Not only did you not get as much, but you were paying more for the extra bag - the lesson there being that multi-packs are not always value for money. Shopping has become a maths project (and I don't do maths well), but it's also become less expensive!
