When you get the delivery bag from the postman at Dragon Roost Island, you can start the merchant trading quest. If you have the Delivery Bag, Zunari will give you a Town Flower.
There are three merchants who will trade things with you. One is on Mother & Child Isles, one is on Greatfish Isle, and one is on Bomb Island.
