Billionaire Mark Cuban has admitted to shopping at one specific department store - and he's even revealed what he buys.

The businessman might be of staggering worth now, but he wasn't always so wealthy.

In fact, during a recent appearance on the Club Shay Shay podcast, he opened up about how he landed his first big deal in 1990 and what he spent his earnings on.

Cuban explained how he had just sold his first company, a little software startup called MicroSolutions.

The deal was secured by CompuServe, who bought the business for $6 million.

He ended up getting drunk with his friends to celebrate when they asked him: "What do you think you’re going to do with all this money?"

Cuban said: "And I’m like, ‘I don’t care about cars or houses, but boy, you know, I fly a lot for work'."

Cuban drunkenly went on to call American Airlines, where he spent a whopping $125,000 on a lifetime flight pass.

He explained: “I got all that information, hungover as hell, and I signed up. Initially, it was $125,000 and then I upgraded it. I forget how much I paid, but it gave me almost unlimited miles for me and somebody else for the rest of my life.”

Despite his now monumental worth, the Shark Tank star has revealed he still shops at Target, explaining he likes it because he can 'buy anything' there

"I can buy birthday and holiday cards, T-shirts, some electronics and toys," he told the Daily Mail, adding: "Basically stuff you realize you need in the middle of the day."

He also revealed it's super convenient for him, because it's only around a mile from his home.

Cuban is currently an investor in the business reality TV show, Shark Tank, but the billionaire will only appear in one more season.

He explained he's moving on from the show in order to spend more time with his family - wife, Tiffany Stewart, and children Alexis, 21, Alyssa, 18, and 15-year-old son, Jake.

"I love the show in every way. It has inspired a generation of entrepreneurs and yes, I will miss it," he said.

"I wanted to spend time with my kids before they are on their own."
