Scary marketing observation #4124. Last

Scary marketing observation #4124. Last week, my girlfriend bought some Campari, an alcoholic ingredient for mixed drinks, at the local Trader Joes, and today we get a huge promotional brochure from the Campari Corporation. We've never, ever gotten any advertising in the mail from this or any other drink company. So how'd they know? Well she used a credit card, and all we can gather is the Campari Corp. does some scary, aggresive marketing.
