It was innocent enough, I was at the cash register buying a book and the salesperson asked if I would like to give my postal code for a $5 credit on my next purchase. Why not, I thought to myself and I walked out of the store a happy customer. Or so I thought. Next morning, I’m reading my morning paper and I see an article on how companies that know your postal code can do all kinds of things to you! Quite anxious, I went to our IT Guru, Mike, to see what I had just done. The conversation went something like this:
Me- “Mike, I gave a company my postal code. Did I just sell myself?”
Mike- “It depends. Did it feel good?”
Me- “Mike, I’m serious. I got a $5 credit and they got my postal code. What does this mean?”
Mike- “It means that you’re a very cheap …”
