Those who open a dollar store soon find that it is a constant challenge to keep every type of merchandise always in-stock. In some cases there are merchandise availability problems. In others it is a matter of decisions about what to buy and when to buy it. In still others it is simply that there was an unusually high number of purchases.
No matter what the cause, when you open a dollar store you are responsible for insuring that your store is always stocked. To make sales, there must be merchandise. Even more important is that the merchandise must be what the customers want when they come to the store. If you fail to have the right items in stock, customers will go elsewhere to buy.
