Barnes and Noble shows why tracking is bad and the mild implications it can have.  Why would I want them to track my purchases?  Who else has access to my purchases?  That's plain evil!  I guess the lesson here is, don't buy where they "temp" you with like-purchases.  Now, had I bought a CAR, which is $14K - $65K, I might understand a couple of years later, they send you a card wondering if you might want to "upgrade" or "upscale" your vehicle.  When they track $5 purchases, that is truly scary.  What then does the grocery store do?  Do they send me carrot coupons because I buy a lot of veggies, or new BOLD laundry detergent advertisements?  Tp Barnes and Noble for a year of spamming and now purchase tracking, I give an F or single finger flying flag, if you get my metaphor.
