OS X High Sierra

I am trying to update from macOS Sierra 10.12.6 to 10.13 and I can't find 10.13. Well, yes I can, but it takes me to either the app store or iTunes, and both tell me that it is no longer available in the US. Sooooo, how do I get that upgrade? I have a Mac Pro 2010 w/o a 'metal' graphics card, and High Sierra is the newest that I can install.

Mac Pro, OS X 10.11

Be sure you have no other macOS installers in your Applications folder. If you do, then move them to the Trash, temporarily. Only use the Safari browser.
