On July 11, 7-11 offers a free slurpee to all customers. The free slurpee cup is a fraction of the size of any of the already-very-cheap options available for sale. I have seen lineups out the door and around the block on this occasion. I think this illustrates very well people's well-known tendency to irrationally value free stuff. |
