For those who have switched over from PenFed Cash Rewards to PenFed Platinum Rewards.... it seems that PenFed is planning a change to the Platinum Rewards program. On the website, it shows that beginning in 2014, gas purchases will be reduced from 5 points to 3 points (per dollar), and supermarket purchases will be reduced from 3 points to 2 points. Based on the website, it does not appear that there is any changed planned for the Cash Rewards card (which earns 5% cash back on gas). I called customer service, and they seemed somewhat confused and unaware... they didn't seem to really know whether the Platinum Rewards changes would reflect only new cardholders, or whether the change would apply to existing cardholders as well. They also don't know whether or how the Cash Rewards program would change.
Anyway, to play it safe, I cashed in all of my Platinum points and then asked them to switch my account back from Platinum Rewards to Cash Rewards. They weren't sure if they could do that, but eventually it went through. (You may recall that when they originally introduced the Platinum Rewards card and gave us that bonus for switching, they also said no one would be allowed to switch back.) It seemed like a good idea to switch back anyway, since cashback on my statement is better than their points, which have to be redeemed for gift cards. That being said, I now noticed on my credit reports that it reflects that they closed my Platinum account and opened a new Cash Rewards account, which of course was not what I was looking for on my credit report.
