So retailers are given data about you to better target ads, which earns you coupons to shop at those same retailers? Am I being too cynical here or is this just the next evolution of the coupon packs that I get in the mail every week?

One of the reasons I don't want targeted ads is to avoid the manipulation that can lead to spending more on stuff I don't need. Giving discounts attached to those targetted ads just seems like even more manipulation.
