Several years ago, the BW points were providing me a lot more opportunities to get good value out of them -- and so I would buy them when they came up on Daily Getaways sales. I have no interest in doing so any longer with BW points, as both of the following (which were applicable a handful of years ago) are largely just history for me:

(A) part of it was that I had the run of the lot to pick the best rooms using points at a bunch of BW properties; and
(B) the other part of it was that my target destinations/properties were a good deal using purchased points.

Given both A and B have been gutted, the value in buying BW points is not what it used to be for me.
