Received a pack and the stealth basically comprised of a ziploc bag inside a letter. Now, I've only made a handful of DNM purchases but they've all been vacuum-sealed, pack-inside-a-pack-inside-a-pack ad infinitum, etc etc etc. This thing even has customs declaration on it, how did it make it through? Like I laughed when I opened it, wow.
Depends on what your definition of "normal" is. Is it safe/right/good business? No. Does it happen often with new/dumbass vendors? All the fucking time.
Name and shame. Do it.
