Things not to buy
Ready meals. convenience food, pre-prepared food.
Cook from scratch, buy large tubs of yoghurt, or even better make your own.
Branded groceries - go for own brand or value brand.
Expensive cleaning products and detergents. All you need are washing up liquid, vinegar, bicarb, washing soda and maybe bleach. Cut dishwasher tablets in half. Buy a huge box of Aldi/Lidl laundry powder and use a bit less than the recommended. Pretreat stains.
Lunches/sandwiches out. Make your own for pennies.
Snack food. Pop your own popcorn, make your own flapjacks (while something else is in the oven), oat cakes etc. Compare the cost weight for weight potato crisps vs potatoes. Cheap cream crackers with smudge of butter or wafer of cheese are good.
Expensive cuts of meat. Eat mince based meals, bulk out with red lentils for bolognese, kidney/haricot beans for chilli, put a layer of baked beans under a shepherd’s pie. Get cheap cuts of meat that need slow cooking like pork cheek, ox heart or beef shin. Cook 2 or 3 days worth to get value from extra fuel use.
Breakfast cereals. Eat proper porridge, toast, or even better something protein based but cheap like eggs that fill you up longer.
Mobile phone contacts. Try to extricate yourself if you are in one. If you are (nearly) out of contract go onto GiffGaff if you want a rolling monthly package bundle. Ask a friend for a recommendation code… you’ll both share bonus credit. O2 is good if you want a cheap classic ongoing PAYG. Ideal if you’ve downgraded to a basic Nokia/Alcatel handset. Try to use skype etc when connected at home to wifi to call people.
Takeaway coffees. Buy a leak proof flask like a Contigo. I think Morrissons do a cheap version for around £5. Buy an Aeropress for £25, or a French press from a charity shop and make your own fresh coffee in the morning.
Meals out. Stop these, unless it is the birthday or anniversary of someone in the immediate family. If you are socially obliged to go, just drink water and order something simple like a starter + side dish.
Takeaways. Buy a copy of “The Curry Secret” and/or “The Takeaway Secret” (v cheap paperbacks on amazon) and make your own. Make up batches of curry house style sauce and freeze.
Magazines/newspapers. Read online. Go to the library.
Entertainment/media packages. Try to cancel if you can. Otherwise try to renegotiate how much you pay and what you receive. Even try to get rid of your TV license - just watch Youtube etc and buy cheap DVD’s from the charity shop/borrow from the library/friends. You don’t need a TV license as long as you don’t watch live broadcast TV or BBC iPlayer.
Books. Borrow from library, or buy cheap from charity shop.
Adult clothes, unless worn out. Mend and darn small holes - tutorials on youtube. Look first in charity shops/Ebay/FB local selling groups.
Don’t put the heating on or up till you’ve put on a thermal vest, jumper and cosy house socks. If you’re extra skint, wear a beanie hat, snood and wrist warmers & wrap up in a fleece/heated duvet.
Shop at Aldi/Lidl for basic groceries then visit one of the main 4 at teatime-ish to get final reduction 10p bargains on meat/veg/chilled foods/bread.
Use less toiletries - eg a pea sized blob of toothpaste is fine - just enough to foam up and taste minty. You don’t need to double wash your hair, if you’ve got lots of lather cut back. Bar soap is more economical than shower gel and leaves you feeling cleaner.
