Pizza Hut is awfully proud of its claim that the pizza chain is responsible for the very first Internet purchase ever made. And now to mark that mushroom, pepperoni and extra cheese pizza back sold 20 years ago in 1994, Pizza Hut is offering 50% off online pizza orders through January 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 press release. “We’re doing so by giving back to our customers who have helped us lead the way with digital innovations over the last 20 years.”

So what’s the catch (because of course there’s a catch)? You’ll have to sign up for Pizza Hut’s Hut Lovers email list and loyalty program in order to get the discount on any large or medium pizzas.

Want extra cheese or a $10 dinner box? No discount on either of those.

And depending on the franchise near you, there might be a minimum order requirement to get the discount or that location might not be running the promotion.
