So in one world, Maine emails back "that report costs $750. Agree or disagree?" If you agree, you mail them a check, and two weeks later they process the payment and send the report. Apparently that's ok.

But it's kind of slow and tedious. They can expedite the process by just including the report. Open if you agree. Delete if you don't. Or even defer the decision until later, but there's an "instant unlock" option available at any time. That seems a lot better than the above alternative.

Maybe Maine flubbed the implementation, but it seems like a "for your consideration upon agreement" facility should exist that doesn't require multiple round trips. Certainly more convenient than the alternative.
