To try and maximize revenue on this load the company places it's available space on a 14-day calendar. They send an e-mail to their customer database. To entice buyers they have the price drop rapidly at the beginning of the calendar and level off toward the end. They have nothing really to lose since they would otherwise be making nothing additional on that shipment if it goes out half empty. The item will not be FREE at the end of the calendar.
Initial price opens at low price and rises to a peak.
From this point the price declines to a minimum acceptable price where it remains for the duration of the auction. A passenger cruise ship launches their summer vacation packages with an advertising campaign in June. Knowing passengers do not book early they introduce pricing on a 90-day calendar at a low price and hold it there for 30 days. Knowing demand will increase as the market becomes familiar with the deal the cruise ship decides to increase the price of their packages for the next 30 days. As the date of the cruise approaches the carrier begins lowering the price incrementally and does so for 15 days since a majority of their ship has been booked and only limited choices are available.
