half-off any regular-priced pizza on their menu that you order online.
While I shouldn't have to explain more, this is valid for small, medium, large, even extra large sizes. Pick from cheese, pepperoni, combination, Hawaiian, thin crust... I haven't had Domino's in years and I'm tempted to try it. With half off it's a price I'm willing to risk.
