Here are some of the things that I do...

Use lots of generics
Walk instead of driving (good for health too)
Take my lunch
Wait an extra 3 days to go to the grocery store - and make some creative meals in the interim
Make home made bread
Go out to cheap restaurants (Chipotle, etc) vs. sit down ones (also good for diet)
Order one meal for 2 people, often portions are so big it's OK
Give up on competing with the Jonses...we don't need a new car, books, movies, etc. all the time
Don't go to the movies. Rent them. Or skip them altogether and take a walk.
