Let's re-do this and make everyone happy, 'kay? Only one exists on the market, being passed between two people:

The Original Owner (EFF)'s trade: http://www.tf2outpost.com/trade/9851526

Wants 5 and 20 Keys Pure; rejects an offer that adds up to 5 Buds and 10 Keys by ICConquest.

The Broker (Katniss)'s Trade: http://www.tf2outpost.com/trade/9864542

Asking for 6 Buds and can go down to 5 and 20 Keys; rejects an offer of 5 Pure and the same offer of ICConquest's.
