You have to admire Taco Bell's marketing move.  They stole a good deal of publicity with the free crunchy taco they are offering every American on Tuesday, October 30th between 2pm and 5pm. It was a marketing ploy around the World Series.  All any player had to do was steal a base and the offer was on.

Will a lot of people take Taco Bell up on the free taco?  You bet.  And it won't cost Taco Bell much.  Come on, one little crunchy taco? Pennies per for them.  Plus, there will be long lines at the fast food restaurants and you can bet a good number of those hungry patrons will pony up a few bucks to buy additional items.

It just goes to show that your "free" offer doesn't have to be really big.  It just needs to give the impression that it is.
