2 months old price. This is a case of bp.tf following the price, not driving it. They are selling for 1-1.5 keys on market, buyers are buying cheap and flooding the market.

Autobumped, unsold >1 week, seller is not afk:

http://www.tf2outpost.com/trade/12463186 - sold 1 of the 2 in the last 2 days, but the buyer is selling for 2 now (so probably didn't sell for 2 keys)

http://www.tf2outpost.com/trade/12248332 - 2 weeks

http://www.tf2outpost.com/trade/12273186 - 2 weeks

http://www.tf2outpost.com/trade/12364509 - 1 week

I honestly think the real price on these is closer to 1.75 flat than 1.75-2. But it's hard to say since there are a few sales at 2.
