This is a bit off topic as I want to talk about Discover, but:
In Japan, online merchants that accept both JCB and Diners Club may not accept Discover. case in point: Amazon.co.jp
I tried to ask Discover and Amazon.co.jp the right questions but didn't get back the right answers. So I wonder if anyone here knows: Is it the case, outside the USA, that Discover should be accepted as a Diners Club?
