Nebulous
Legend
I introduced a limited magic item shop in Port Nyanzaru when the PCs were stopping at civilization one last time before heading to Omu.  They had a bunch of accumulated items and wealth they wanted to trade for useful stuff.  I had to wing my way through the whole thing, and I definitely didn't let the players cherry pick what they wanted, and that IS what they wanted to do.  But they were dealing with a wealthy Merchant Prince who had a market on magic, so it made sense within the context of the adventure that there would be stuff there to sell/buy/trade.
