Yes, for me there is. Here is why:
I can only speak for myself, but I have recently discovered that second hand shopping can really get out of hand, and in terms of the amount of stuff that accumulates, it is potentially a lot worse than even mindless H&M shopping.

I end up hoarding a terrible amount of (albeit lovely) stuff because it is available, because it is second hand, and because it is cheap. The end result is still consumerism. I spend money on stuff I don't really need.
Of course I feel better for spending money on second hand than cheaply manufactured, child labour stuff. However, the space in my closets runs out just the same. The pictures above are just the tip of the iceberg. An entire room in my flat is dedicated to my flea market project: sorting old stuff, pricing it, packing it. I take a couple of Ikea bags to the local self-service flea market almost every week. My closets are still full.
