The Anger is constantly in demand, but the current price is accurate (surprisingly). You can barely go a single day in the servs without someone coming in spamming the text chat that they're buying one. The reason you see such a wide price range on this hat is because the majority of people buying it do not use outpost. They are usually new to the game and want it for their Sniper a.s.a.p. There are two completely different price sets; one in the servers, and one on outpost. In reality, the causal maps and trade servers see this being sold from 2-2.3, and only on outpost do you ever see the 2.6-3 range. Although popular, there's no reason to bring up the low end on this hat because they are simply too available (coming in around 50,000+ unique) and commonly sell for less.

A bunch of your previously unsold at 2.66 are now sold. However, sales at 3 ref seem to be lacking.

I guess it is pretty fair to raise the price, upvoted
