Have separate bank accounts for different things. We have bills/DD, Food/petrol, school stuff, holidays, days out, summer holidays, big purchases and savings. On payday we each put in our contributions. Then divide disposable income by two.
Save for Christmas all year. I treat this as another bill and have a standing order go into Christmas account every month.
In Jan I buy a supermarket gift card and put £30 a month on it until October/November this takes care of food and drink for Christmas
On a work day keep only £5 in cash in your purse.
Take packed lunches, drinks and snacks to work and on days out. Food on days out is vastly over priced.
Shop online for groceries. Swap to own brand _most own brand is fine.
Use Costco once a month to buy things like washing powder, loo roll, bread, cereal in bulk.
Meal plan, lunches and dinners for seven days.
I only buy three breakfast.cereals porridge oats, wheat biscuits and cornflakes. Used to waste a lot of money buying different cereals the children liked that they never ate.
Cook from scratch where possible.
Pulses to bulk out meals
Meat free twice a week.
Something on toast once a week
Use washing powder instead of liquid tabs or tablets. Use half recommended dose of powder. Dilute softener.
I have ditched expensive beauty products used to buy high end and it cost £££. I now use organic castor oil to cleanse, diluted witch hazel to tone and astral cream to moisturise face and slap on some SPF sun cream skin is fine and I have sensitive skin.
Use re usable sanitary towels honour your flow I think are good ones.
Have gone back to using bars of soap instead of £££ shower gel that just was money literally going down plug hole.
Baby powder is good as substitute for dry shampoo.
Buy in charity shops.
Always buy the best quality bra, coat, shoes, bed sheets/duvet covers and towels that you can afford. They last longer in my experience.
