Walmart and H&M destroy unsold clothing

A story was just written in the New York Times about how large retail chain stores like Walmart and H&M destroy and discard unsold clothing rather than donating them to organizations like The Salvation Army. At these large chains where the clothing is so inexpensive to begin with, I guess there's no point in shipping items to discount stores; but I never would have thought the clothing would just be discarded. It turns out that H&M has machines specific to damaging the clothing: for example, a large hole at a shoulder seam; a missing sleeve; or a torn pair of pants. The store then deposits plastic bags full of these goods behind the store to be picked up by garbage collection. I'm sure they'll change their ways in some way after this NYT story has come out but, it makes me want to reconsider patronizing the chain.
