I was wiped out financially after my divorce and had to watch every penny. I got rid of every 'luxury' I had taken for granted:
Daily newspaper 70p+ per day = £5 a week = £20 a month = TV licence
Water meter cut my bills from £40 a month to £12.
Packed lunches saved me £3 a day = £21 a week = my council tax
I even worked looked at the way I drove - drive slowly, brake slowly in advance and use the gears saved me £20 a month in petrol.
Home hair dye = £5 rather than £50 plus at a salon.
My car insurance shot up by £120 for no reason - shopped around got a cheaper quote and spoke to my insurance company. They matched it on the spot - no further admin to do and saved £30.
Wear clothes more often without washing. I don't smoke or work in a smelly environment and I shower every day and use deodorant. A tee shirt can go for two or three wearings before washing. Knickers and socks can't though!
Never buy dry clean only clothes.
A £4.99 tomato plant will give you dozens of tomatoes throughout the summer.
Take extra care of your teeth - floss and brush every day to avoid dental care costs.
Look up the website for Four Ingredients or Less or something like that for cheap and easy meals using errrmmmm four ingredients or less.
Going shopping with a friend to take advantage of the two for one offers so you do not end up with an overload of shampoo/rice etc.
Look up recipes for sauces rather than buying ready made. Some sauces are sold for £2 and you can make them for 30p.
