As I have been reading this thread I came across one that I do yearly or twice a year. Call all the companies I get a bill from (land phone, cell phone, cable, internet, etc.) and see what promotions are out there and where I can cut my bills.
My DH just told me something was wrong with the phone yesterday, b/c it is only saying "incoming call" instead of what the number actually is! I told him, I stopped caller id, call waiting, etc. and am saving us $15 a month. Then I added that I cut our cell bill by $20 just be reducing our minutes that we NEVER used and our Cable bill by decreasing the speed of our internet service ($10) which I don't even see a difference in! That's $45 a month I saved for the coming year (or $540 this years!)
It's always good to read these threads! Thanks for all the good tips!
