A few examples:
Return library books on time. Library books are FREE. But they aren't free when you forget to return one of the CDs in a 2-CD set, tell the husband, forget again, and don't return it for another month. Trust me, I've been there. It would've been cheaper to buy that CD in the first place.
Don't hang onto a gym membership you don't use. If you haven't been to the gym more than one time since before you got pregnant in November 2008, CANCEL THAT MEMBERSHIP! (yes, this is also me speaking from experience...)
Eat, cook, or freeze your food before it expires. I talk a lot about stock-piling and buying a lot of something when it goes on sale. But that only works if you're going to use it or do something with it so that it will keep until you use it. You might find a great deal on a big butternut squash, but unless you use it before it gets funky (do squash get funky? I might find out soon enough...), it's not a savings if you weren't going to buy it in the first place.
Don't buy items just to use a coupon on it unless it's somehow going to make you money or you're going to use that item. I've done it. I've gotten sucked into those MEGA SALES (and yes, that deserves all caps), bought all sorts of things I *think* we'll use, but then they expire. Or we find that we're getting fat because I'm
Trust me on these. I've done them all (not the throwing away money, though...how crazy do you think I am?).
And I'm going to try to remedy them all by the week's end. Wish me luck.
What sort of things are you needlessly spending money on?
