This free Domino's pizza offer is a tad different than the freebies we're used to, so I'm going to quote their page.
When a pitcher throws a no-hitter this season, visit mlb.com/dominono and enter your mlb.com account. After each of the first 2 no-hitters, the first 20,000 mlb.com users to enter their mlb.com accounts will receive a code valid for a free medium two-topping handmade pan pizza.
So what you want to do today is signup for a mlb.com account. It's free and should only take a minute. Then, when the first and second no-hitters are pitched this season, I'll make two posts reminding you to go grab your pizza!
Think there won't be a no-hitter pitched this season? Well, history says otherwise. We had three last year, seven in 2012, three in 2011, and six in 2010. In fact you have to go back to 2005 to find the last season without one!
