I buy them 1 wep each, resell at 1 scrap. Haven't had a problem

Perhaps a change to .05-.11?

Also, the unbox value of them is about 2.33 ref.... or more than what your expected return is on a crate #1. Perhaps a few more days so the price of it's contents drop, but not yet

EDIT; Was just dumped with 150 of these at a weapon each. Not enough to sway me juust yet, but I would agree sellers seem to favor 1 wep to 1 scrap.
