You posted an excellent question.
It would be GREAT if we could get some Amazon employees to give us an answer to your question.
Here are some things you could do.
@papyrophilia @Rushdie and @Oneida_Books seem to me to be the keepers of Amazon e-mail addresses. I think there is an e-mail address, maybe it starts with pq-(?), you could write to that Amazon e-mail address and ask.
What I have been promoting and so far and Amazon has not implemented is, Amazon provides a forum on the bottom of each help topic. It would work this way, you read the help topic and it does not answers your question, when you get to the bottom of the web page for the Help Topic there is a space to “Ask us a question.”
You write in your question and an Amazon business employee answers your question, Not a contract employee but an actual Amazon employee out of HQ answers your question. It would be like a limited forum on the bottom of each Help Topic page.
Once a question has been asked and answered by Amazon when another seller ask the same question the second sellers question gets deleted. In other words every question gets answered once, but not every seller gets their question answered if Amazon has answered the question previously.
Should Amazon implement this feature on Help Topics it would be a help to the Amazon business as they would for the first time see right in the help topic where their help topic is not written clearly. Amazon would see because of the questions they are getting that the help topic is not written completely enough to answer sellers questions.
Pointing sellers to the Amazon Forum is inefficient for Sellers as this forum has various levels of other sellers knowledge and ability. What we sellers actually want is an answer to our question directly from Amazon, directly on Amazon’s Help webpage.
You have asked a really great question and hopefully if I tag a couple of mods they will come and answer your question for all of us.
