Back-to-school means cheap pizza for fans of Domino’s. The chain announced this week that its stores nationwide will offer 50% off menu-priced pizzas ordered online from August 26 through September 1.

The promo could affect smaller independent pizzeria operators who already struggle to compete with the national chains. For them, here are 15 tips for outmaneuvering the pizza giants.

“It’s back-to-school season, which means there is a lot to do in a short amount of time,” said Jenny Fouracre, Domino’s spokeswoman. “Between buying school supplies, clothes and dealing with schedule changes, there is little time for much else, but Domino’s wanted to make one thing easy: planning dinner. Not only is pizza night perfect for those busy days, but now it’s also half off when you order online.”

The 50% off deal is only available on menu-priced pizzas ordered through any of Domino’s online ordering channels, which include their website (dominos.com), as well as Domino’s ordering apps for iPad, iPhone, Android and Kindle Fire.
