In the chart below some examples of hot points are given. In most cases adding or selling additional products can mean earning more than or at least the cost of the products ordered, meaning you could be leaving "free" product on the table.
In the $440 hot point example below a representative with a $420 order is at a hot point. If she keeps her order the same she will earn $147 at 30%. BUT if she adds just $20 in products she will instead earn a 40% commission and her earnings will increase to $176, that's an extra $29! If the additional $20 order was from customers that's an extra $29 in the representative's pocket. If she ordered $20 worth of product for herself and her family, not only are those items practically free but she has a surplus of $9.
Pay careful attention to the size of you order and your earning level. You DO NOT want to leave money on the table.
