As a business, we must understand the marketing tools. I ran a snack at the snack bar line above the supply of snacks, whether domestic or imported. But anyway, snacks comparison is relatively small goods, if sold one by one, then profits will be relatively small. Itself is equivalent to my shop is to focus on sales, sales of goods are the same nature, and I want a set sales approach, is to the same goods are packed into a group of a group, and then to sell, so you If want to eat this thing, at least to buy a set, and snacks for a group of consumers who love to eat snacks may not eat.
