I have used the bonus points mall several times over the past couple months on items ranging from a SPG hotel booking to tooth whitening gel.
Rarely if ever have they posted. Used the link, paid with plat. Pretty much nothing yet besides a few points fromba B&N purchase.
Rarely since last July have I gotten the points.
It's really not worth it to me to make a fuss at the moment. But there definitely needs to be an overhaul, at least if my experiences are indicative.
