Abstract: Graphical user interfaces (GUIs) for providing multi-parameter offers to users are provided. Such GUIs not only efficiently present a particular multi-parameter offer, but also provide insight to the user as to other multi-parameter offers that could have been offered instead, thereby allowing the user to gauge the relative value of the offer being made against the potential other offers that could have been made. Such GUIs are arranged to present the information regarding the offer parameters in a space-efficient manner that allows for such information to be presented for large numbers of potential offers, e.g., 50+ potential offers, in a small display area, e.g., a smartphone screen.
