Last year, when they raised prices, they just increased the incentive amounts for the first period following the increase. But, as I recall,
if you looked at the net price per point, it was still a slightly higher cost than the last incentive period.
With few exceptions, when purchasing at an actively selling resort, there will never be a cheaper time to buy direct points than the current incentive period.
That said, it does feel psychologically satisfying to straddle one incentive period to another and helps you feel like you did the get the best deal available to you at the time.
