Hello, John.

This service looks like something I would like to use, but I'm learning that international transactions can be an inconvenience. They are a bit pricey, to my point of view, but - it might well be worth it!

However, I still feel it useful to ask - do you know of any similar services in the USA?

Not only can they seem pricey (that may be partly to do with being London based), but I've also found that the prices on the website are not always up-to-date, and in those instances the bill comes to more than you expected...

Still, the service is excellent, so I'd give a cautious recommendation.
