Growing my own food - a greenhouse and a large veggie patch. Plenty of onions, leeks, rocket etc. Salads, chillies, cucumbers, courgettes during the summer. A glut of home grown tomatoes from June to October, so I've frozen masses of basic tomato sauce for the winter. Frozen apples, cored & sliced. All virtually free.
I order flour in bulk & make my own bread which halves the price. I made enough bramble jelly & wild plum jam to last us a year, which cost 4p a jar.
Adapting food - buying chicken legs rather than breasts, watching for special offers - eg, ducks were on offer so I've two, frozen ready for xmas, at 1/3 price of a turkey or beef. Cook from scratch, it's less expensive, healthier & tastes better. I've got quite good at meals that take less than 15 minutes effort. Eat veggie once a week. Shop in indian supermarkets for spices which are silly price in Tesco. I've cut my weekly food bill by about £20, or £1,000 a year
Wearing a sweater & socks at home in the evening. I haven't turned the heating on yet, but that will change the moment there is a frost forecast. 😁
No mortgage so no big increase there. I parkrun rather than gym. Weights & resistance bands at home.
Like a PP, I refuse to give up my regular cut & colour, but the salon has moved to cash only to avoid bank charges and keep prices down. I do my own nails & brows.
No skiing holiday but I'm planning a really good Christmas to cheer everyone up.
