BUT I have managed to get about £200 put away, and I haven't done a "big" shop yet. I have still, as I said, got plenty of food in the house, but it just needs to be supplemented. I will have to go shopping at some point, probably today, because the lunch boxes were a mighty struggle this morning, and it defeats the object if child B asks for money to buy a fruit bag from the canteen!
So, challenge abandoned for now, but new lessons learned - and it does not mean a licence to go mad in the shops - I will continue to buy just what we need for the next few weeks, so that I can put more money in the savings, and then I will go back to building the stores up for the winter - the longest day is here today, so the tide is turning again, back towards the winter. Can't believe it is the longest day already!!
