"we do not send items to landfill in the UK"
We send them to landfills in China.
It boggles the mind to imagine that millions of brand new items are destroyed. Why ? Can't they just stay on the shelves until they get sold ?
This is clearly the worst aspect of our wasteful society. We make things, use resources, and destroy them before they can ever become useful.
If Amazon has so much stuff it can't sell, it should seriously review its decision process on what items it acquires in the first place. And, if an item really does not sell well, then bite the bullet and put it in the dollar bin at 99 cents. I'm pretty sure that you'll ship a lot more and won't need to landfill them.
