Taco Bell was having trouble with Monday because on this day people usually decide to save money by taking lunch from home. Sales on this day were worrying. So, Taco Bell decided to make a promo of four original tacos for one thousand colones.We made a campaign of radio teasers in which each day of the week confessed its defects, and in the last spot, played on a Monday, we presented the promo. After this, the individual spots were aired with the sales line included. We also opened a Twitter account so that Monday could demonstrate that he was better than he seemed, thanks to the promo from Taco Bell.
