The items they sell to Link and their prices vary from a merchant to another.

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.
