Scammer, do not deal with this user.

They will tell you that escrow is ok, but they are lying; User explained to me that Lutpin is not a trustworthy Escrow and that they would attempt to contact their own escrow. Tried to change the terms we had already agreed on for days; the second I got an official escrow to agree to handle the trade safely, the price was suddenly unreasonable (even though it was what they offered me), I merely accepted their offer. Then they claim it's not worth it after they realize you won't do a deal with their sketchy escrow, accept their unsafe escrow terms, or accept a price they know will make you run away from the deal once it becomes too hard to scam.

I agree with xBox, OPs trusts are sketchy, his actions scream "Scammer!", they do not hold their word, they lie and manipulate in an attempt to steal your items/codes. Do not deal with this user, I have forwarded this information to a few DT members and I'll be making a thread in Reputation to see if this kind of behavior can be exhumed.
