When we want to have "girl's time" we go to breakfast instead dinner - much cheaper! When the weather allows, I ride my bike to work, there have been weeks when I didn't sit in a car until Sunday (groceries), my 2nd job is also only 2 ml away.
Other thing same as above: brown bagging, no sodas, Aldi shopping, ignoring the posts that tell me that Target went 90% - I probably don't need it if I don't already have it, and those 10 or 20 $$$ add up!
