Dynamically modifying user interfaces according to predicted user preference

摘要

Disclosed are various embodiments for generating customized user interfaces including offers for items available by multiple merchants in an electronic marketplace. A search of an item database is performed in response to receiving a search query. If an item is available from multiple merchants in an electronic marketplace, a user interface element including selectable components for a subset of the merchants is inserted in proximity to a presentation of the item in a user interface. Interactions with the user interface element can be used to predict a preferred merchant of the user.
