Yellow sticker reductions for meat or ready meals. Freeze for another day.
Cook big casseroles and soups from scratch. Portion up and freeze.
Use birthday or Christmas money on season passes to a local attraction (or buy instead of loads of toys). Mini morning cinema is good value.
Charity shops are full of lovely stuff where I live. I got a brand new high end makeup set today for £2.
Walk if possible to save petrol money.
Invite friends with children round for lunch rather than meeting in a cafe or pub. More relaxed, children entertain each other, much cheaper.
Join the library and use it.
Cut down on snacks, alcohol and soft drinks. Healthier, saves a lot of waste (wrappers, cans etc) and saves money.
Use soap bars, shampoo bars and conditioner bars rather than liquid versions. Basically you are paying for the water that's been added to it, the packaging and the cost to transport the extra weight. I started my first shampoo bar 4 months ago, wash my hair every 2 days and it hasn't run out yet!
