Nope. You can usually spot scams from a mile away. And I don't buy from sellers with bad/no seller feedback, which is a pretty reliable way to avoid scammers. There is a chance that anything could be a scam, but it's unlikely for an account that has sold plenty of legitimate items to suddenly start scamming.
I bought some Etymotic earphones from a 3rd party seller on Amazon one time because the price was so good. But there is a chance that they could be fakes, although they look real enough, the price did seem a bit too good to be true. They sucked anyway (turns out I really don't like "neutral" sound) so I suppose it doesn't matter if they were. Poor quality cable that started fraying quickly. Never had that happen to me with any other headphones. I suppose it's due to the rubber (silicone?) material they used. Anyway, I digress. So I guess that's a "maybe" on getting scammed on Amazon, but most likely not.
I have been accused of scamming though. When I had some OnePlus One invites and tried to sell them off for a few bucks each, a few people thought my $5 listing was for an actual OnePlus One device (because that makes sense...), I had made the title "OnePlus One Invite" and selected the phone from a list which made eBay insert pictures and specs of the actual device, which apparently was a bad idea. Some of them got pretty mad and accused me of scamming etc. It was my first eBay sale, cmon guys, go easy on me
Because of that, I had to refund all of them, and the invites expired before I could sell them again, so I only actually sold one, the last one I did, where I put more clearly "INVITE ONLY" in the title, and made the first picture a screenshot of the invite page. That seemed to work.
