I do, 99+240=339. 339/24 = 14.125. Then add in that you can buy the points and membership with gift card and that brings the cost per point down further. I have plenty of points but I don't even think my direct points cost me less than 14 dollars per point. I use them on the summer trips, this year because we're WDW locals, we're using the points on passes.
With the renewal being 987 for cash per pass and 65 points per renewal.
987/65 = 15.18. 15.18>14.125. So it's worth it to buy the BOGO points. Currently keeping the cash means more to me than the points and it's nice to avoid having to rent them out and etc.
