Abstract: The optimization of fulfillment option benefits is described. In one example, selected offers for items are assembled for a transaction. A fulfillment option benefit, such as a delivery or shipping benefit, is identified for a first one of the items. A system determines whether an offer for a second one of the items contributes to qualification for the same fulfillment option benefit. When the offer for the second item does not contribute, the system searches for any other second item offers that do contribute to qualification for the benefit. If multiple other offers are found, the system ranks the other offers to identify a preferred other offer for the second item. The system then calculates a difference between the originally-selected offer and the preferred offer for the second item and generates a qualification contribution notification that highlights the preferred other offer as contributing to the fulfillment option benefit.

Abstract: An improved mechanism is provided for presenting and navigating bookmarks in a set of electronic reading material (ERM). In one implementation, when a portion of an ERM is displayed, a graphical element, which represents the contents of the ERM, is also displayed. A current location indicator and one or more bookmark indicators are further displayed on or within proximity of the graphical element to show where, within the ERM, the currently displayed portion is located and where bookmarks are located. This provides a useful graphical overview to a user. In addition, the mechanism may facilitate navigation to a bookmark by enabling a user to select one of the bookmark indicators to navigate directly to that bookmark. The mechanism may also enable a user to navigate sequentially from bookmark to bookmark using a previous bookmark control and/or a next bookmark control. With these capabilities, bookmark presentation and navigation are improved.
