I had a craving for ice cream, so I decided to get some. I was standing in the Target store aisle reading labels, comparing the fat content of the different brands. I chose Haagen-Dazs because it has more fat and less carbs. Turns out, I like it. Since I've lost 20 lbs and weigh what I did 20 years ago, I figured it'd be OK.
Well, the brainiac mathematicians behind Target's famous big data operation appear to have me dialed in just right. When I bought the 14 oz ice cream, the register spit out a coupon for $1.50 off when I buy 3. So on my next trip, I bought 3. And then the register spits out a coupon for $1.50 off when I buy 4. Interesting.
Offended by this turn of events, I buy none on my next trip. But eventually I succumb to the temptation and I later buy 1 using no coupons. Then I get a coupon for $1.50 off when I buy one. Not 3, and not 4, but 1.
Target is working hard to feed my new Haagen-Dazs addiciton. I think I may have gained a pound. A pound of delicious high-fat creamy goodness.
