Made a cock up with my bank account (moved last month and had to go to Uncles funeral overseas so lost track) and I realise I now have £190 til the end of Sept to buy food and petrol for the 4 of us.
So....after filling the car (essential) which will cost £40 I will have £150 ish left.
I still have to buy nappies, wipes etc out of that too. On the plus side, just bought loads of cleaning stuff so should be ok for that.
£150 for 3 weeks for a family of 4....oh crikey thats only £50 a week isnt it??? 
Any tips?
Still need to buy fresh fruit and veg for dc as well as do packed lunch for ds1 each day for school.
Other than using up stuff in the freeezer and eating lots of soup & jacket potatoes, what else can I do??
