Merchant

Merchants are recurring characters in the Zelda series. They first appeared in, though an unrelated character appears in.

The Legend of Zelda
In, Merchants can be found either in caves or underground. Their shops are located in 12 areas in the First Quest and in 15 areas in the Second Quest.

The items they sell to Link and their prices vary from a merchant to another. There are four types of merchants: the ones who sell Magical Shields, Keys and Blue Candles; merchants who sell Magical Shields, Bombs and Arrows; the ones who sell Magical Shields, Food and Hearts; and only one merchant in each quest who sells Keys, Food and Blue Rings.

Trivia

 * In The Legend of Zelda, depending on which defensive ring Link wears, the clothing of the merchants changes to match the color of Link's tunic.
 * In A Link Between Worlds, the Lakeside Item Seller in Lorule will complain, "... Ay lliw nihtemos yub...", which is in reverse, "...buy somethin will yA ...", if Link examines but refuses to buy an object.
