What are some money saving tips that you use?

I do a lot of different things. I am actually trying to find new ways to make/save money this month and am calling it my $5 challenge. There are some ideas in my article here: http://gomestic.com/personal-finance/five-ways-to-save-money-on-your-electricity-bill/ and I am also being careful to do the usual things: pack my lunch every day, buy things on sale, clip coupons, and drive less.
