^The Love Estimator: The people who order the heart shaped
   chocolate candies for the stores to sell have a very interesting
   job: They have to estimate how much love there will be each
   Valentine's Day. They have lots of tools for the job -
   statistics, buying patterns, etc, so their guess is usually
   pretty close. So: Do you want to know how much love there was
   this year? Go to your local big chain pharmacy and see how much
   chocolate is on clearance. That's the love that WASN'T in the
   air this year. And while you're at it, pick up some of that
   leftover love at greatly reduced prices.^
