Another saving tip
The same kind of thinking applies to a wide range of things. Other examples are: shaving foam, toothpaste, milk, sandwich spreads... the list goes on. A slightly less obvious example of the same thing is the length of your phone calls.
Use 10% less, 20% less, or more on each of these things and you'll save of money over time. And with this sort of thing, you really won't mind the difference. I can't say it bothers me having slightly less lather in my hair at shower time!
By the way, I added you to my Links list. Thanks again for the link back too.
