A consumer who wants to consume a good at a particular period may
nevertheless attempt to buy it earlier if he is concerned that the good will
otherwise be sold. We analyze the behavior of consumers in equilibrium and the
price a profit-maximizing firm would charge. We show that a firm profits by not
selling early. If, however, the firm is obligated to also offer the good early,
then the firm may maximize profits by setting a price which induces consumers
to all arrive early, or all arrive late, depending on the good's value to the
customer
