I noticed something peculiar that I can't figure out. You can find items like cell phone batterize sold via Amazon at discounted prices. So, lets say you but the item. With your purchase the seller includes a link to his business web site. But on his web site he is selling the same, or similar, batteries at a higher price. What is up with that ? Why would they sell the item at a lower price through Amazon ? It doesn't seem to make sense when they can make more money per sale selling it directly at the higher price ? Can anyone explain this phenomenon ?
