The Merchants are characters in The Legend of Zelda. 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 is four types of merchants: the ones who sell Shield, Key, and Blue Candle; merchants who sell Shield, Bombs, and Arrows; the ones who sell Shield, Food, and Recovery Heart; and only one merchant in each quest who sells Key, Food, and Blue Ring.
