In grocery markets, price variations are often observed for the same item offered by several groceries. This has led to many consumers paying high prices because of the search costs associated with obtaining price information. In this paper, we present PricePoints, a system to help consumers determine the best available offer and thus save their money. To do so, PricePoints compares several items in a number of grocery stores using multiple criteria in order to guide the consumers to select the best product based on their preferences. The system uses a novel algorithm that is based on multi-criteria including item price, its availability, grocery distance, and reputation. The paper presents the design, implementation, and evaluation of the PricePoints system. The obtained results indicate that the proposed system provides justified and reasonable recommendations for consumers in selecting their preferred groceries.
