Abstract: The present invention relates particularly to a system and method for providing product data for use in on-line product catalogs used for promotional schemes, such as loyalty and incentive schemes. Loyalty and incentive systems are well known, where participants gain virtual currency which they can use to purchase goods or services. The present invention enables a plurality of on-line catalogs to be constructed from a stream of supplier data. Selection criteria are used to select product data from the supplier data to go in each catalog. The product data can be updated in real time for each catalog on the basis of the selection criteria.
