Thanks for starting this thread.
My dh replaced all the light bulbs inside and out last year with the new florescent ones. I was amazed at how it lowered our electric bill. I buy most of my groceries at Wal-Mart or Aldi's except for meat which I buy when it's on sale at other stores or buy in bulk at Sam's. I'm buying more store brands now which I never liked before. I've found that it just takes getting use to. I cook enough for two meals and that eliminates the urge to eat out. Today pork loin was on sale so I'm making barbecue with trimmings for supper and this weekend we'll have a sandwich plus I'll freeze the left overs.
I don't run errands as often, try to do everything that needs to be done at one time. I'm also grooming Scooter now.
