About Cheapest Places To Buy

From time to time I read different blogs on the internet, and one I enjoy is Mark Cubans blog. He wrote an interesting post the other day, titled  The Best Investment Advice You Will Ever Get. He makes a few good points, but here is the one that really caught my attention:

"Cash Creates Transactional Returns.   What does this mean ? It means that you should analyze what you spend money on over the course of a year. You will get a better return on your money by being a smart shopper and taking advantage of  cash, quantity or other types of discounts than you will in the stock market.  Saving 15pct on the $1k dollars worth of items you know you will absolutely spend money on is a better return on your money than making 15pct in a year on a $1k investment  because you don’t pay taxes on it."

That really, really made sense to me, and got me thinking. How much money could I save in one year, if everything I bought, I made sure I got at the cheapest price possible?
