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.
