OK. Thank you for explanation!
I haven't seen this; "If you dont have metal/keys or they are not enough we could accept these items at these prices".
We can close this.

Look at this guy http://www.tf2outpost.com/user/176990
He has 25 trades with the same items in the right sides.
I reported him and the answer was: "The trades are very explicit, only the trade notes below are the same."
Yes they are explicit, but only in the left sides. When I want to buy ToD ticket and place ticket in the right the result is his 25 trades one after another.
And he sell the items in the left for metal, not for the items in the right...

Can you explain me how this is not relisting?
