Luckily the exchange worked. Last time I had a fake on ebay they took my money, asked me to ship the product back and never refunded me. Ebay plays innocent and incapable to do anything.
Amazon’s used marketplace has similar issues, but Amazon enforces refunds. I once brought a typewriter that was used, but advertised as “like new.”
What I got was broken (shipped loose, in a cardboard box), and filthy (it literally looked like someone puked on the keyboard).
I did get a refund, but the vendor ghosted me. I had to exercise Amazon’s guaranteed refund. Once I started that, the vendor contacted me, and I was able to return the item (packed better than they did), and get a refund.
Because Amazon's so bad as everyone is detailing here I have started buying much less expensive stuff on eBay where I'd only buy it on Amazon from a 3rd party seller that ships direct, things like books and CDs. Have had uniformly good experiences without paying as much to pass through to Amazon vs. eBay.
