The majority of everything on Amazon seems used. I stopped buying electronics from them (unless it's something cheap I don't care too much about) and I buy directly from manufacturers or walk into Best Buy and buy it new. Hard drives, memory sticks, GPUs, monitors/TVs, and headphones from Amazon are a hard NO from me. The chances of them being used or outright counterfeit is ridiculously high now. Pretty much everything I purchase from Amazon these days seems to be used or fake. This includes something as simple as Vitamin D supplements, where you can tell the packaging has been tampered with. Sometimes I even get consumable products where the seal is gone or has been torn in half.
I wish I had a better understanding of the bimodal distribution of customer satisfaction with Amazon.
I know high volume customers who have 99.5% success with Amazon orders, and others who would say "pretty much everything I buy is used or fake".
First assumption is that it boils down to differences in product types. Certainly some types attract more seller fraud. But I wonder if there's also a region or distribution center variability, like the East Cupcake Regional warehouse does a crappy job of inspecting returns. Or the delivery manager in West Cupcake hires crappy drivers.
Amazon must do this analysis internally. I'd love to understand it better.
