The power of an online coupon was demonstrated by Domino's Pizza which gave away 11,000 free pizzas because of a never used promotion, that a savvy web surfer stumbled upon. Apparently, the company had prepared an internet coupon for an ad campaign to begin in December but which never was activated.
Someone discovered (on March 30) that the codeword "bailout" was good for a free medium pizza ordered online. The info spread throughout the Web until the code was deactivated 24 hours later.
Some Domino's franchisees gave away over 600 free pizzas. This is not really as bad as it sounds - Domino's received excellent publicity not only for it's pizza but also for its new online ordering system.
