It's upgrade time, and I saw the option to pay for it from my Amazon account. Great! I have a balance there from a recent return and I'd love to use that for my KBM upgrade.
But when I click to use Amazon Pay, I get the error message:
It's as if it tries to go to Amazon and fails, returning without a payment method chosen because I never got shown that dialog. I've tried being signed in to Amazon when I do this and it still doesn't work.
The FastSpring site says it should be seamless.
What am I doing wrong? Or is there something wrong at FastSpring? Maybe it only accepts full purchase and not the upgrade discount?
Impatiently,
August
