After seeing willwar's thread about the Marriott being a range of APRs based on creditworthiness, I got curious and jumped on Chase's site and checked out the other cobranded cards and it looks like the Amazon visa also has an APR range now.
Indeed, the Amazon Visa has had an APR range for many years now. I don't remember what mine is, but it definitely wasn't a single APR card from Chase.

If a bank can find a way to make more money they will. It has hit the CSP/Marriott so far and pretty sure it will come to the other cards from them sooner than later that had a set apr.
What will be intersting is to see if the existing cardmembers will be grandfathered in or if they are to expect an apr increase if they don't meet certain criteria.
Then, can we expect an apr reduction if score improves?
