They used to give you a point if you failed to draw, but now you have to go online separately to buy points. The online option to do that is now open...
I got a PP from last year, because I applied for a 0% chance unit as first choice, and a 100% unit for second choice.
This spring I read about the change -- that you no longer get a PP if you don't draw your first choice. I didn't want to use my point yet, and figured I'd get a second point this year just by buying it in July. I applied for the same unit I hunted last year, still a near 100% draw unit with 0 points, as my first (and only) choice and drew.
Just went to buy my PP and found that not only can I not buy it, since I drew my first choice, I no longer have the one from last year. It was burned on this year's 100% draw.
I should have read more carefully I guess. Basically lost two years of PPs.
So it's too late now, but for the future: if you want to hunt AND get a preference point,
you still have to apply for and not draw a first choice unit. Then later you have to go buy the preference point.
