Is there anything you do to be frugal?

I am learning all sorts of new things about being frugal. Here are some of the latest:

• Get free magazines and blockbuster rentals from coke by entering their reward codes (if you don't want yours give them to me...hahaha)
• DVD's at our library (I think I mentioned that ours is online and you can request movies and they call you when they are ready for you - so cool and free)
• Signing Bean up for kid's clubs at the mall and favorite shopping spots - we get all kinds of goodies and coupons
• Freezing leftovers when I make a big batch of something yummy
• Using coupons everywhere (I heart coupons and if you don't you should)

I have a lot more to learn in being frugal so let me know your tips!
