Just today I'm returning something. I was trying to buy more of the sort of underwear I like. But I quickly end up in the junky end of Amazon where the same product is listed under slightly different names by different sellers and the interface gets all weird. It must have done that thing where you pick a size, then pick a color, but it automatically adjusts the size to whatever's available in that color. So I ended up with 3 2-packs of too-small underwear. And one of them came without the manufacturer's packaging, just two pairs of underwear in a baggie. Because that's not suspicious or anything. Now I have to package that stuff and haul it to the UPS store.
And I'm totally with you on the advertising. I get how they got there, with a bunch of teams optimizing short-term micro-metrics. But apparently nobody cares about the overall experience.
Three weeks later, suddenly the seller adds tracking to the Paypal claim, and a few days later the part that I no longer need shows up in a Newegg box. No invoice, packing sheet, etc. and it's still not listed on my Newegg account. My claim gets closed, and there's nobody I can even return this to.
What a stupid, stupid situation.
Newegg has not said anything about this to me, nor explained why after a Newegg transaction my card was cancelled defensively and reissued.
I haven't been able to trust Newegg in a very long time, which is sad. They used to be the gold standard, now it's a decrepit pit of dropshipping garbage.
Where do you go for computer stuff that you can trust these days? Every box in all the Fry's stores around me all seem to have already been opened and returned twice by the time i see them.
It is at least possible to filter it to items only sold by Newegg.
Counterfeits: yes of course, just as many if not more
Multiple listings for the same product with different prices: yes, it's by design!
Advertising: not as much, but it is present
Fake reviews: the product reviews on eBay are mostly useless. The only thing you can rely on is the seller reviews
eBay has some newer product-focused pages and features, but they don't create the kind of problems you see on Amazon.
It also seems somewhat harder to keep creating new seller accounts on eBay. I've been ripped off several times by highly rated sellers on Amazon that disappeared after a several weeks long case pending against them. Amazon resolved it satisfactorily, but it meant that I would have gotten the item faster from China.
All my personal experience, of course.
Of course ebay listings have multiple products, but not in the same super confusing way you see on Amazon.
"mixed reviews and the unknown of which seller is more likely to ship a good product" - Being unsure of which seller is best also exists on eBay
I don't think Amazon's listings are confusing. You usually have size and color variations, and sometimes things like multi-packs. I guess that is subjective.
Newegg went the same path like Amazon and I have stopped using them. They used to be my favorite store.
