I've certainly seen marketing discussions of too-low pricing. I haven't worked close enough to retail or marketing to know anything more than what one hears, though.

I would expect people looking at your book on Amazon to have some rough idea who you are. The number of books on Amazon is so high that not many people will end up at your book purely at random. If they get there via reasonable connections, most will have seen your name. And, at least on the cover shown, it mentions NYT bestseller, which pretty much establishes that you're not some self-published fly-by-night. (Doesn't, of course, prove much about whether person X would like your books, or whether they're "good" according to some objective standard other than high sales numbers.)
