Plan weekly meals around grocery ads.  Stock up on expensive things (like raw almonds) when they're on sale and then store them in the freezer in managable portions.

Jen, the coffee at home thing has been a big $$ saver for me this year!  Great tip!

Soooo true!     We are doing this a lot now that we're in a house instead of apartment.  The first two electricity bills were  .  I think we're getting the hang of it now.

Very good advice!!!  It's amazing how much those fees are now; plus the ding on the credit report that goes along with them.

I use public transporation and only use my car on weekends.

Take advantage of things work pays for.  For me, we have a pre-tax transportation benefit.  I use that, then I also get reimbursed for if I pay for a Metrocard or use my car to go see a client.  I often end up MAKING money from this benefit.

My work also pays for my cell phone.  (I guess my point is, check out what your job would pay for for you!).

I don't have a 401K but people who do, often say this is the closest thing to "free money" a job can give you.

If you go out to eat, or dinner at a friends/family, bring leftovers home!  This often goes for lunches/dinners for a couple of days.

I like the financial threads.  I am sure I can come up with more stuff later!
