Feel I should name change, as I'm likely to get flamed. It's about spending well and also financial literacy. (This really should be taught in school, so please support the Mumsnet/MSE campaign on this).
I cook from scratch, mainly veggie, buy from greengrocers, don't have takeaways.
All our clothes etc. come from eBay or charity shops - often virtually new. I never buy me or DD books but get everything from the library. We go to the cinema regualry, but the £1 show on a weekend morning.
Sorry to sound smug, but things like this really do save money. They are also environmentally more friendly. Echo LilQueenie (must be a name thing) - freecycle, vouchers, moneysavingexpert newsletter.
A car gets you from A to B, holidaying in the UK is expensive - going to SE Asia can actually be cheaper (seriously).
Also, if you are £3000 in debt, you would be better extending your mortgage by £3k and overpaying as you will save money.
