Jeff, the owner of the toy box (a toy store), has chosen his products carefully. they are all handmade of wood; none are cheap games made of cardboard and paper. he knows he will be selling his toys to both adults and children; for example, his expensive chess and backgammon sets are quite expensive because the board and pieces are all made of wood by local artists and craftsmen. he knows that his customer base will not include parents who are looking for an inexpensive toy for their children or to give as a birthday gift; there is another store in town that offers mass-produced games. as part of his marketing outreach, jeff offers "game nights" where he sets up game boards and invites local teens and adults to take part in light-hearted competitions, where the winners receive a 10 percent discount to a game at the toy box. all of jeff's activities are aimed at giving jeff a sustainable competitive advantage through
