I think BW bulk is still considered new for this, and may not rise for some time, especially with the undesirable (imo) holo design.
There is someone on pokebeach trading for it, but US only.
You can check out my Trade thread, I am also trading for any and all Bulk (including Japanese). I haven’t updated it in a while, but you might see some stuff that interests you!
