Systems and methods for facilitating an on-line purchase of at least one item on behalf of a consumer are disclosed. A consumer may shop and purchase at least one item on a consolidated shopping (CS) website displaying one or more items available for purchase on one or more different merchant websites. The CS website provides consumers with advanced searching that takes into consideration a personal profile of the consumer, the consumer's previous shopping history, transactional data relating to a group of similar consumers, and the like. A host computer providing the CS website may access a merchant website selling the requested item, and order the requested item on behalf of the consumer, and charging a transaction fee, listing fee, receiving a rebate and/or offering a rebate for performing such. One embodiment allows a consumer to purchase/order multiple items from multiple websites in a single purchase request to the CS website.
