I've had 0 scams on Amazon in 15(?) Years of using it. I had one "new" product that was clearly opened, and two clicks on their website later I had a pickup ordered from my door the following day and a replacement in the way.
So I bought a six pack of socks off Amazon once. Seemed like a low risk purchase. They arrived looking like any other sock. New packaging, didn't see anything wrong with it. Socks looked new.
They didn't feel new. You know that new sock feel you only get fresh from the package, before they've been washed? They didn't have that.
I don't know if these were factory reject socks that failed QC after the fabric softener ran out or some sort of counterfeit sock or just some sort of error that could happen anywhere, but I will never forget my Amazon marketplace betrayal.
My point was about Amazon itself, or, at least, items shipped by Amazon. I only buy cheap junk from marketplace sellers, and even then, only if they ship via Amazon.
Never had the slightest issue with creating a fully-paid return label on my own. And if the products aren't very expensive, they don't usually wait to actually receive it before issuing the refund.
Other sellers are usually hit or miss, requiring jumping through hoops, like calling them up or filling half-broken internet forms and waiting around for them to "approve" the return.
Putting on a brand new pair of socks, fresh from the package.
They took that away.
It's like taking a bite of delicious cake only to find out it's shit. You can send it back to the kitchen, but it doesn't take away the whipsaw disappointment.
That's why people praise it.
