Slightly tongue in cheek, but in the spirit of the thread, become a fancy tea drinker instead of a fancy coffee drinker. No expensive machine needed and you can still buy nice bags or leaves, which are cheaper than coffee. Is also cheaper from cafes and you can ask for 'anything from Bird & Blend' for Christmas/birthdays etc.
Walk or run for exercise and use the equipment in parks for strength training. I have two that are about half an hour run/walk away so can run there, use the equipment and walk back. You can also keep an eye out for the things people leave on their front wall to give away. I've had a few things like that.
Buy normal broccoli instead of sprouting, it's about a quarter the price by weight and tastes similar enough.
If you can get to them easily, look in Heron, Home Bargains, Farm Foods etc for anything that's cheap (I pass the first two on the way home from work). Best bargains for me are the proper Spanish allioli in the yellow tub that's about half the price of the supermarket in HB and Spice Tailor kits in Heron that are usually about 80 p instead of £3 ish.
Become a Stoozer. I earn around £500-1000 a year by borrowing money from credit cards interest and charge free and putting it in a savings account.
