He is right a lot of people are trying to sell for 2 keys and succeeding but please provide evidence.

I do not think that this is worth this much.

Why? Well look at my trade:

You can see that the current lowest offer is 1.33ref, which is half of what you are suggesting. Also, the trade currently has 1134 views which may indicate that there are A LOT of people who are trying to get rid of their "souls".

Also, you have no evidence, not even a word on why it costs this much. On top of that, you have 1 if your backpack... -_-
