A web site user interface for an e-commerce retail company allows a user to easily browse or purchase products or services offered by the company. The web site user interface can include a dual horizontal navigation bar including a main navigation bar and subordinate navigation bar. The subordinate navigation bar can be actively and passively customized. Further, the subordinate navigation bar can include product shipment information in a user specific notification pane. The web site user interface can also include a drop-down logo from the dual parent navigation bar where the web page continues to include the drop-down logo as the user scrolls down to focus on web page content. Alternatively, the web site user interface can include a main navigation bar and secondary navigation bar where the main navigation bar includes fewer subcategories of products than the secondary navigation bar.
