"When we're home, we're home," Giuliana tells PEOPLE

Bill and Giuliana Rancic have a secret to a fresh marriage: a dish by their front door.

“The minute we come home, all our phones go in there,” Bill, 44, tells PEOPLE. “That way, we’re not texting or emailing people at work. We’re interacting with each other. It was hard at first, but we got used to it.”

“When we are together, we try to keep the quality time at a 10,” adds Giuliana, 40. “A lot of people, when they’re home, they’re not really there. They’re checking their phones; they’re distracted. We try not to let that happen. When we’re home, we’re home.”

“Obviously, emergencies come up,” she continues. “And we’re both very understanding of that. But you know, a lot of things that you think are emergencies really aren’t. They can be handled later.”

The Rancics will be moving to Chicago full-time this summer, in part because it will be a great place to raise their 2-year-old son, Duke. They also say it’s a convenient, central location from which to run their many businesses.

“Aside from all the TV projects, we have two booming restaurants in Chicago, RPM Italian and RPM Steak,” says Giuliana. “We’re opening another one in Washington, D.C.”

“We’ve got a production company, as well,” she continues. “We have a show on Oxygen coming out soon. I’m on HSN in Florida. We’re partners in a wine company called XO,G, which is available in Walmart.”

One thing they try to avoid: wasting time.

“When I go to work, I work,” Giuliana says. “I don’t surf the Web, call my friends or socialize with other people. I usually eat lunch at my desk. I’m there to work. That way, I don’t feel guilty when I’m home and my phone is in the dish by the front door!”

PEOPLE caught up with the Rancics at the fifth annual Runway to Hope Spring Fashion Soiree, an event that raised more than $1.2 million for families affected by pediatric cancer. It was the second time that the Rancics hosted the charity event, which was founded by high-profile attorney and business entrepreneur Mark Nejame and his wife, Josie.

“It’s really important to us to work with charities like Runway to Hope,” Giuliana says. “When you get down to it, this is the most important thing we do.”

“Everyone’s busy,” Bill adds, “but this is something we have to make time for. There is always time to give to others.”
