A system and method for querying, selection and ordering complex multi-component item packages using a personal computer communicating over a global communications network. The system prompts the user with interactive staged queries on the intended equipment use, location, type and relative equipment quality requirements, for instance. The system determines the required item components of a package that correspond to the user requirements by referencing an expert system database which contains a listing of items. The user may then choose the entire selected package of items or delete any items not needed and then place the order. The selection website has interchangeable framing for access from another website in a manner transparent to the user.
