I ditched Kroger in (IIR) the late-ish 90's. The were just rolling out their first loyalty/discount card program, which would record all your purchases.<p>In-store, the people trying to sign me up for the card swore up and down that all my purchase data would be used for absolutely no purpose whatsoever.<p>Talking to business publications, Kroger's Investor Relations people were bragging about all the uses that they would be making of their customers' purchase data.
