But after getting burned a few times with products that did not live up to the standards presented in bogus reviews or product rankings, now I only use Amazon for the fast shipping. Instead of spending the majority of my time on Amazon doing the research there, I'm spending it on blog posts, reddit, or YouTube looking at real testimonials and going to Amazon only when my shopping is already done. Those extraneous checkout-line addons are no more.
In this way, Amazon definitely does itself a disservice by (seemingly) shifting their priorities away from what they used to excel at to more "big picture" ideas.
I'm only one customer, but clearly I'm not the only one with a growing frustration, and this case (since that's the only one I can attest to) they're losing real money, and I would cause that a disservice.
