Merchant's Oath

A Merchant's Oath is a binding verbal contract between two merchants, formed by trading one product for another. Link is first introduced to the concept by Zunari, the proprietor of a humble stall on Windfall Island, who asks him to negotiate supply contracts for him with Traveling Merchants. Once Link trades an item with a merchant, forming such an oath, the merchant will thereafter ship their products to Zunari's shop, increasing his product line. He gives him a Town Flower to trade for another item, which begins the Island Trading Sequence.

Whenever Link encounters a Traveling Merchant while on the Great Sea, he can form a Merchant's Oath with him and receive a variety of items, depending on what he has to trade. The Traveling Merchants honor their oaths by sending their items to Zunari's shop via Postman.
