Repackaging...

I'm curious as to what everyone's thoughts are on this topic. Is it ever okay?

If I purchase pigments from TKB Trading in bulk amounts and remix the colors and sell, is that considered repackaging? I haven't actually done this, but I'm just wondering what the guidelines are here in the pigments world.

If I specifically purchase bulk amounts of say.... MAC and intend to sell them in samples, is that considered repackaging?
