Is this dynamic currency conversion? I guess I'm a little confused by DCC. I always thought that was when they give you the option to pay in your home currency rather than just telling you are paying one price and billing you another.

Per the screenshot, although they had just told me I owed 600, they actually deducted 658.40. They then sent me a receipt saying I had paid 600. All within a matter of seconds so obviously the exchange rate hadn't fluctuated that much.

And this one is small, but I've made 50 bookings with them this year! The cost of some of the deposits (Japan, Hong Kong) were quite substantial so I'd say they are pulling in quite a bit through this.
