I have used of GCs from Staples over the past year. Now somehow even though I have 12 Credit Cards in my Amazon and Amazon Payments Profile, I am able to use only 6 of those to send Payments. Even when I add a new card, it does not show up as an option on the drop down menu on the payment screen. I have been checking every day for the past week and this is not going away. So essentially I can only use those 6 credit cards and I can not use any other. I have also deleted several cards hoping it will resolve it but that has not worked.

Anyone else had similar issues? Any recommendations? Any prior reports of such an issue?
