Even though DCC's may only be in the low single digit percentage of the bill, it could actually be a huge difference in a business' margins. I would not be surprised if this becomes more a norm rather than the exception.
I guess it's time to for me to apply an Amex with no FTF.
When using Amex to avoid getting charged the DCC, you do not really need to ask for another slip, right? You just give them your card and Amex processes the bill without the DCC?
