Trading Town Banners

I have a New Magencia and a Skara Bra banner I would like to trade for another city.

Is this part of the storyline finished?

Dont think so, you can still get a banner once a week and I think you can still do new towns.

unless they have patched it since you can't place the banners unless you're able to buy them anyways (requires same loyalty amt) so there may not be much point to trading.

Really? Did not know that - thanks.
