You only have to select to receive a preference point for sheep, goat, and moose, as those cost $50 resident, $100 non-resident, and you can opt out of paying the fee if you do not want to purchase a point, many high point holders are opting out of the fees because they dont think the value of weighted points is worth it.
For deer, elk, bear, pronghorn, you are automatically awarded a preference point if you do not draw your first choice, or if you select points only for your first choice. You can still draw subsequent choices and earn a point.
