Secondary use of your personal information

How many times a day are you asked for your email, telephone number, postal code, or birth date? Probably more than you might realize. Think about when you go to the grocery store, the pharmacy, or to a clothing or electronics store. Many retailers ask for your email to connect purchase history with future promotional offers to better tailor potential discounts with your spending habits. But is this legal? Well, it all comes down to the purpose for which the information was collected.
