set sales

I really want to move back home to the supermarket, then I open a supermarket, but I do not have much money, so can only play a minor to get a store open, but the store’s business has been increasingly dismalbecause too many things missing my little shop, and even is no shortage of things, if there were no guide is really difficult to find, later, to change this situation, I see there is a marketing book called the set sales,I according to this marketing store things integrated classified, after I discovered that the business is up, turnover is also rising.
