I could be wrong, but my understanding was that, at the larger chains,
information collected via the scanners is centrally collected and 
stored, in aggregate fashion, to make wholesale purchasing decisions.
However, in many cases, specific client files are built using special
identifiers like coded coupons, checkout cards, and so forth.
