Sometime it just pays to check and re-check the normal things that you buy.
I was walking down the cereal aisle yesterday to get some cinnamon toast crunch and happened to catch the store brand out of the corner of my eye. I didn't have any coupons, so I wasn't buying the name brand anyway - but I was actually going for the econo-sized cereal in a bag.
Well, I saw the price per ounce and compared it with the bagged cereal and to my surprise, the store brand was cheaper!
Moral of the story: keep checking those prices - with the economy in such a state, things are changing!
