when whips dropped from 1.7m to 1.6m i ran into some guy saying ' I buy whip 1711k'. So first time i put in whip, he puts 1711k, clicks accept, but then decline. I'm like what the heck?! he says: "Lagged wtf :S" So we trade again, and of course i'm thinking he puts 1711k again, so i accept two times (too fast). when i look in inventory i see 1171k :S 550k gone :(
