Things that have helped me single mum of four.
Pay off debt quickly and first over savings money.
When you start saving put this is a separate account on payday and forget it.
Don't use tumble dryer I use a heater airer instead or line dry. I do miss the dryer though.
I do one big monthly shop in Asda for around 200. Then I hide most in cupboards. Take a few bits out each week for snacks. I then spend 30 per week on fresh items fruit and milk etc. this stops me running out of stuff and going to the shops and buying crap. So monthly food is around 300-350 which isn't bad for 5 with all the cleaning bits.
I don't by brand anything food wise.
Cook a lot from scratch. Egg on toast or beans on toast is an ok mela over a week or noodles with frozen veg and a sauce.
I bake a lot as the oven is on once a day and it's cheaper than buying a cake.
Lidl for baking ingredients
All my clothes are from a charity shop for me
Exercise at home no gum membership
Free days out
Don't have a car on finance
Own brand washing powder etc is absolutely fine I find the Lidl one good
Use soap not shower gels and hand washes lasts much longer
Lidl and Aldi face creams cleanser etc are all good.
Buy uniform when sales are on. Re use last year's I see no point in buying new for September just replace what needs updating.
Take water bottles from home everywhere
I never buy lunch at work. I make a smoothie at home using frozen fruit and have that for lunch Monday to Friday.
If you pass a garage that's cheaper for petrol fill up there the difference can be enormous
Holidays are euro camp which are really reasonable and good fun
Don't drink alcohol often
I get home stuff in charity shops like art and old cups and saucers but that's my style I don't like new stuff.
Think about everything before you buy it often you don't need it
