Then there is the not new, new items issue, which is like you got a cheeseburger, but someone else got it first, licked the bun, decided they didn’t want it and returned it to the counter.
For all of the billions of dollars Walmart is spending trying to be like Amazon, this is the one area they can nail Amazon directly in the gut. Amazon’s entire cashflow positive low margin growth model falls apart if Amazon was the one that had to try to be like Walmart. Once consumers think of Amazon like eBay or Craigslist, the cost to reverse that view will be massive or impossible. Ironically, I get electronics that are in great shape and undamaged from eBay, not the same experience from Amazon.
Right now Amazon is a giant flea market. It’s on par with Craigslist, and a little worse than eBay. When you buy something on eBay you know who it came from. Amazon, you know nothing. Try ordering 5x of the same thing from Amazon and see the wild variations in quality and condition they are in.
I've had the same experience as you. I'm not sure what the cause is (maybe there's lower volume, so scammers don't use eBay as much), but I've bought things like top-of-the-line noise cancelling headphones refurbished at huge markdowns on eBay and had zero issues, but I've not had great experiences buying similar things from Amazon.
I'd argue eBay is actually safer than Amazon now, because at least the reviews are less sketchy and easier to trust and also buyers can self-select from more legit products by going for higher prices. And can guarantee you're buying from the same seller every time who will ship direct to you.
Whereas for things like makeup on amazon even if you choose higher priced you're still at risk of getting knockoffs due to comingling.
Even if there are no complaints but simply a higher than average return rate, Amazon will shut down a listing, and this is done based on the actual supplier of the stock, not the commingled seller. Source: have gotten such emails from Amazon when I was selling that specifically said "you may not have actually sold the orders these complaints are for but it's your inventory".
Reviews shouldn't be used for describing problems with the seller, anyway. Use seller feedback for that.
"For inventory tracked with the manufacturer barcode, each seller’s sourced inventory of the same ASIN is stored separately in our fulfillment centers. We can also track the original seller of each unit."
It creates a natural "market for lemons" experiment on Amazon. I can't imagine that is healthy for Amazon in the long run.
My orders/year and dollars/year at Amazon are <50% what they were a few years ago.
Amazon is no longer the first place I look for many items; with things like Shopify, high-quality eCom experiences are available to basically every business in a way they were not 10 years ago. For branded products, I’ve started buying direct from the brand websites with mostly good results. I’ll probably cancel Prime next year.
