My tile exchange is located at the Cat's Paw megalopolis.
I sell tiles at two prices, 25TN for tiles I cannot bake myself and 10TN for tiles I can bake myself.
I don't trade in TN directly, but I price goods generally at the prices available on atitd.info. I'm most interested in fine glass rods, paints and gem cuts needed for a wind chime, and petroleum currently. I also like mushrooms (EoO and other moderate to rare shrooms).
