I could agree with this price for these first days. I've seen people offering Triad Trinket clean, 1 key + 2 ref, 1 key and so on, and sellers refused (crazy guys :p)

I got one for 2.66 ref within an hour. The 1-2 key range was probably valid when it was suggested, but 9 hours later it's already outdated.

It seems with a quick outpost search most people are trying to get 2 keys, I really want one, but I know it's going to go down fast like the FaN and the tomislav

As Eman said, this is a strating price. Just wait a few days and this item will drop like hell (seriously, how many people use the homewrecker :D)
