All of them show him being sold for 1 key. Evidence seems solid. Upvote.

1 & 2: Sold for 1 key.

3: Unsold for 1 key.

4: Bought for 1 key (scroll down).

5: Unsold for 1 key.

Very convincing. The ones that aren't selling for 1 key and the fact that people are willing to pay said 1 key makes this a very strong argument for a decrease in price. I really hope these keep dropping, my friend got one for 1.33 ref and I'm vexed because I want one too...

I bought one for 2.33 with some waiting, easy upvote.
