Also check items on the shelves below eye level - these brands of products will often be cheaper than the ones you normally see and easily reach. Check it out. AND TAKE A LIST - STICK TO IT, TOO!!!! Have also heard that strangely enough, if you shop counter clockwise OR shop from the opposite end of where you walk into the supermarket (not where the fruit and veg are at the beginning!) you will only tend to buy exactly what you came into the shop for and stick to those items only. Rather than the specials that you didn't actually need or the impulse buys. I find that if you shop within a limited time period ie. you have to be somewhere after you've shopped, then you will buy also only what you need, as you don't have the time to buy or consider buying anything else.
