When calculating how much the bonus package costs, I compare the total cost of the rate that includes the bonus package to the total cost of the rate that I would use if I didn't get the bonus package. Is this the best way to think of the cost of the bonus package?

As far as I can recall, every time I made this comparison, the points were too expensive to be worth it. (However, I do not recall making this comparison during a promotion that increased the number of points, such as the 2x promotion.)
