> I believe they also offer a "stop allowing charges by this merchant" feature If they have this it's another reason to use them for automatic billing. I have tried to do this with a VISA card and they said they cannot do it; the only way to prevent future charges would be to close that account entirely and even then I might still get billed for some period of time.
American Express is a very special card that typically comes with annual fee that is very much worth it. I would never book any hotels, buy plane tickets or signup in any form of membership with any other card because I got burnt way too many times with Visa and MC is even worse. Also that's why businesses typically do not like AE because how easy it is to dispute the charge. But to add - I discourage you from using…
I never knew this! I have heard about companies banning you if you request a CB, which would be really bad for things like Google, Uber, etc.
I usually end up having to dispute a charge only once a year or so. It has surprised me over the past few years how lacking AMEX seems to be in its "investigation". It at least used to take a few days and they'd sometimes ask for documentation. The last one I did got turned around in maybe an hour.
