They're destroying new products too!
You can try to offload it via a box of junk auction, and they do do that, but I'm not sure how tractable it is at scale.
The article is heavy on implication and light on facts.
They are destroying things for a reason, which isn't given. It could be a bad reason of course, but probably isn't.
The amount of retail "wastage" that occurs would be surprising to many - one you may have seen is the "book without cover has been reported destroyed" you sometimes see - it's not worth it for publishers to have booksellers ship back unsold inventory.
Anecdotally, this isn't always true. I have only returned a handful of things over the years, but among them was a microphone windscreen that didn't really fit. It cost maybe €6 or so and they did have me send it back.
I think there's a correspondence between the COVID-19 reduction of their real-human chat line and having us return everything except food now.
For example, I randomly picked a 24V power supply:
https://www.amazon.co.uk/-/dp/B07P4N3H1F/
Cost: GBP 16.99, non-new + GBP 4.99 shipping.
Yet From ebay an equivilent item, inc shipping, is [1] costing GBP 4.43 (brand new). From Aliexpress the item costs GBP 4.87. On Google, there are 10+ companies all offering this device for similar prices.
There is some kind of market failure going on that is allowing Amazon to be substantially higher priced for the same items even when the item is in non-new condition.
It can also result in very good prices when the "new" item drops with a coupon or similar.
Correction. It's expensive in comparison to the cost of discarding (including disposal/environmental damage fees).
Which is something we can actually change.
