Traffic is essential to increasing business.  Lets say you are in a mall versus an outdoor store, you will have increased traffic at a mall therefore more sales.  That is why it is SO much more expensive to purchase a store at the mall.  However, one thing that I have learned, if you are a business owner, a good product at a great price beats out everything.  Make sure you know your product and you will be happy that you know that there are 35 different types of knives that cut a tomato 1/12 inch thick.
