(I tried searching before posting, but did not find a topic that addressed this. Google wasn't any help either, sadly.)
I live in the U.S., and it has always bugged me the way the Harry Potter books were edited for American audiences, with various British terms and phrases being changed because they "wouldn't make sense" to American readers. I want to start buying my own copies of the Discworld books, but I just wonder if the versions published in the U.S. have been diluted in the same way. Even as a kid, I loved reading books by British authors and learning on my own that people from other countries use different words for things, and I hate the idea that people would actually put down a book because they don't know what a "lorry" is, or something.
So, rant aside, can I order the Discworld books cheaply on, say, Amazon.com and get the same books that British readers get, or do I have to order from Amazon.co.uk just to be sure?
