Pizza Hut is offering 50% off online pizza orders through Jan. 10. “We want to celebrate the fact that before consumers could buy books, clothes, music or vacation packages via the internet, they could place an online order for a Pizza Hut pizza,” said Carrie Walsh, chief marketing officer at Pizza Hut in a release. To get the deal, one has to sign up for Pizza Hut’s Hut Lovers email list and loyalty program.
