Riding a bestseller to the top

If you have a bestseller on your hands — in other words, a product that outsells
your other products by a multiple, which means it ought to sell at least
three times as much as anything else ,why not make the most of it? Some
marketing experts look for bestsellers to achieve sales that are at least ten
times the norm; outstanding bestsellers can achieve a hundred or more times
the normal level of sales for a product in their category. If you have just one
bestseller in your line, growing your revenues and profits is a piece of cake.
