Oh see no that is exactly how easy it is to get your stuff on Amazon. You can also sell your Professionally manufactured Tunecore or CD Baby CDs on Amazon with a few clicks. Hell you can sell Posters and T-shirts etc. It is very easy. And Amazon is the largest online retail site in the world. Your claim that it is hard to get physical media into retail is laughable and shows just how clueless you are about the Indie Music Biz.
And yes Amazon will help you market your stuff in the same way they help Independent Authors with the tools they provide to market their stuff through Kindle with social media etc.
Get your CDs into Walmart, Target, Rasputin, and other brick and mortar stores not online digital which have low returns and NO MARKETING except what you do for yourself. . . that's what i am talking about. For every runaway bestseller in the indies, there are a thousand who don't sell on Amazon. You don't realize that. You think that's "marketing" but it isn't. That's putting your car on a corner with a "For Sale" sign and waiting for someone to call you and ask about it. You just don't have a clue about what Marketing is all about. Not at all.
Go back and read what HamiltonJay posted to you above and learn something. . . then read what I have been posting to you about GAAP and learn more. You keep spouting ignorance and spouting and spouting and spouting. It's tiring.
Amazon's help is NOTHING. You said it yourself. The Indy has to do it himself.
