remember all our purchases are very valuable info to businesses. It is not just during online activities; it is also frequent shopper card programs (i.e. grocery store loyalty cards like Krogers, Harris Teeter, Shop Rite, JCPenneys, KMart/Sears, CVS, etc). They know what you tend to buy & at what price point- hence the ads, coupons, facebook ads, search engine info, etc.

It is called Data Mining and involves a lot more than just your address, phone and income. I'm afraid we are a commodity frequently bought, traded and sold - all for someone elses financial gain. {big sigh}
