Can't find post re saddle trade - HELP!?

Saw it earlier this week - someone wanted to trade a San Marco Tri saddle for an another brand. I have the San Marco, and would consider the trade.

I also have a zero degree Thompson seat post that I used for part of last season. Any takers?

What color is the seatpost?
How much were you wanting?

Black - I paid $110 last summer. I would like to get $75.
