There's a difference between "asking for" and "getting." You've posted zero examples, that coupled with me seeing a few sell for 4 ref yesterday gets a downvote from me.

Doesn't mean what they ask for, it matters if they manage to sell it for that price.

Sure people are asking 2 keys but just the other day i bought one from someone that was for 5 ref

What people ask for is rarely what people end up getting.
