Update: in future, be sure to ask about old unused certs...
Hi All,
Thanks for the responses. I ended up purchasing 4k extra points for $50. Turns out there was another way to get the points. For future reference, when I later called the Platinum Premier line, I was told that they can re-credit any old / unused certs. I had an unused certificate from way back in 01/2007, and the lady at the Platinum Premier desk was able to re-credit the points from it to my account. It was too late to un-purchase the points I already bought, but a good lesson for future knowledge.
