An electronic catalog system, which may be implemented as a web site or another type of interactive system, presents context-sensitive information to customers reflective of their prior orders. In one embodiment, when a customer requests an item detail page for a particular item, the system may supplement the item detail page with information reflective of one or more related orders previously placed by the customer. This information may include, for example, an indication that the customer previously ordered this item or a related item, and may include information, such as status information, regarding such previously placed order(s). If the customer previously ordered a related item, the information provided on the item detail page may include an indication of whether the previously ordered item is compatible or interoperable with the item being viewed.
