he said he's almost finished with him chemistry set after he's finished there will be no more DoN collector's out there he quitted trading actually he just wanted a collectors DoN as u can see he's buying at 6 ref instead of 5 or lower which what traders do LOWBALL he is a decent buyer but he is out of 6 ref atm so ur proof is invalid , he has keys which i think he will sell but you cant sell any DoN to him

P.S not saying the 5 ref/Low end price is a lowball : P ,it depends on the item if it is high on demand you are likely to fail to buy it at its low end but you will succeed easily if its like a disgusting hat/misc not poiniting finger on anything :P
