A shopping system and method of for providing inducements to shoppers are disclosed. The system comprises an input device adapted to collect data relating to products purchased by individual shoppers automatically at a point of sale terminal and transmit the collected data via a communication link; a processor in data communication with the input device via the communication link; database in data communication with processor and adapted to store collected data for a plurality of shoppers; and an output in data communication with the processor. The processor is adapted to analyse the collected data relating to products purchased by individual shoppers to automatically identify core product categories by: grouping individual products into product categories based on purchase characteristics determined by analysing the collected data, and determining core product categories by identifying product categories having purchase characteristics meeting desired purchase criteria for a pre-defined market intention. The processor is further adapted to automatically establish related product categories which relate to the core product categories by, for each core product category: a) selecting a product from the core product category as a core product; b) determining a correlation between the core product and each other product purchased in a purchase transaction by a consumer which includes a purchase of the core product; c) determining a correlation score for each other product and ranking correlation scores for each other product from a strongest correlation score to a weakest correlation score, d) determining a correlation point between a strongest correlation score and a weakest correlation score to determine a cut-off of strong correlations from weak correlations; e) assigning each other product which has a correlation score of the correlation point or stronger as a related product to the core product category; f) grouping the related products into product categories based on product characteristics of the related product; and g) assigning these product categories as related product categories to the core product category. In part c) the correlation score is a value indicative of the correlation between a purchase of the core product and a purchase of the other product. The processor also is adapted to create a promotional offer list listing one or more promotional offers relating to core products and related products, and control the output to offer inducements, in the form of one or more promotional offers selected from the promotional offer list, to shoppers to purchase products.
