How to Save Money

[Blueberry]

Inspired by a query and response on here, I'm finally setting up this thread (which I've been thinking about on and off).

For those of us who are hard-up, what are your creative, inspirational, maybe even fun ways of not spending money?

I'll start:
1) I save money on food by picking and eating wild herbs and even just weeds in my garden (UK) / yard (N.Am) I tend to lack energy and an ability to pull through with projects so picking and eating what grows on its own is good for me. Planting and tending a vegetable garden wouldn't be.

1a) Other uses for plants: a friend told me ivy (hedera helix) can be used instead of laundry detergent which I've been trying out but I'm not quite convinced.

2) I'm starting to look for small pets to look after rather than getting my own. This way I can avoid paying for the vet and all food, bedding etc for pets will be covered by owners.
