And, much like self-made millionaire and fellow Shark Tank investor Mark Cuban, O’Leary suggests you choose to pay with paper, not plastic, at the check out aisle.
“My advice, as always, is: NEVER SPEND ON CREDIT,” says O’Leary.
Americans hold more than $1 trillion in credit card debt, and one survey finds the average card user is more than $5,000 in debt.
Plus, using credit can come with additional costs such as high interest rates, surcharges and other fees, like the extra dollar or so a movie theater charges you to buy tickets in advance with a card.
