With an estimated net worth of $400 million, Kevin O\u2019Leary could afford to never cook, clean, or grocery shop for himself ever again. But the Canadian businessman and Shark Tank<\/em> investor isn\u2019t one to pass up financial savings\u2014no matter how small.<\/p>\n \u201cI\u2019m always looking for a great deal, that\u2019s why I\u2019m in Walmart,\u201d he said in a recent Instagram video. \u201cYou know those fantastic black jeans I\u2019m always wearing? That\u2019s right\u2014Walmart special, 29 smackaroos. That\u2019s how you save dough.\u201d<\/p>\n The 72-year-old added that his wife sent him to the store to buy some essentials, including batteries, butter, paper towels, and OxiClean laundry spray. But O\u2019Leary wasn\u2019t about to waste the opportunity to hunt for a saved buck.<\/p>\n \u201cI want to save dough when it comes to paper towels. Check it out. Bounty\u201412+ rolls is like 18 small rolls\u2014I\u2019m going plus,\u201d he said with a smirk.<\/p>\n O\u2019Leary, who owns multimillion-dollar homes in Florida, Massachusetts, and Toronto, has made the point to shop at Walmart on numerous occasions\u2014long arguing that there\u2019s no reason to pay more for everyday essentials when a cheaper option will do.\u00a0<\/p>\n Plus, as O\u2019Leary sees it, there\u2019s no guarantee the money you spend today will still be there when you need it.<\/p>\n \u201cI hate wasting money,\u201d O\u2019Leary told CNBC<\/em> in 2021 after a Walmart run went viral. \u201cI just don\u2019t get why you would do that. It\u2019s so hard to make it in the first place.\u201d<\/p>\n O\u2019Leary is not alone among the ultrawealthy in keeping a frugal streak. Some of the world\u2019s richest people have continued to hunt for bargains and avoid spending more than they need to, even as their fortunes have grown.<\/p>\n Warren Buffett, whose net worth currently sits at about $144 billion, has long embraced a famously frugal lifestyle. The 95-year-old still lives in the same five-bed, two-and-a-half-bath home in Omaha, Nebraska, that he purchased in 1958 for $31,500. Today, the house is worth over $1.3 million.<\/p>\n He also famously used to stop at McDonald\u2019s on his way to the Berkshire Hathaway office\u2014and let the stock market dictate his order. When markets were down, he\u2019d spend $2.61 on two sausage patties. On better days, he\u2019d splurge $3.17 on a bacon, egg, and cheese biscuit, according to a 2017 HBO documentary.<\/p>\n Ikea\u2019s late billionaire founder Ingvar Kamprad had a similar love for savings. Despite at one time having an estimated $58.7 billion fortune, Kamprad bought second-hand clothes and drove an old Volvo.<\/p>\n \u201cI don\u2019t think I\u2019m wearing anything that wasn\u2019t bought at a flea market,\u201d Kamprad said in a 2016 documentary on Sweden\u2019s TV4<\/em>. \u201cI want to set a good example.\u201d<\/p>\n Kamprad also continued working at Ikea until he was 87, more than three decades after he became a billionaire. He died in 2018 at 91.<\/p>\n One of the newest members of the billionaire club, Scale AI cofounder Lucy Guo, is a more recent example of someone whose spending habits have remained relatively modest as her fortune has soared. The 31-year-old has long embraced the FIRE (financially independent, retire early) movement by going to extremes to save money, including buying discounted clothing, skateboarding to work, and booking flights she would later cancel so she could eat for free in American Express airport lounges.<\/p>\n \u201cEverything I wear is free or from Shein\u2026Some of them aren\u2019t going to be that great quality, but there\u2019s always like two pieces or so that really work out, and I just wear them every day,\u201d the billionaire founder previously told Fortune<\/em>. \u201cI still literally buy buy-one, get-one-free on Uber Eats.\u201d<\/p>\n<\/div>\n\nFrom Warren Buffett to Scale AI\u2019s Lucy Guo\u2014even billionaires still look for ways to save<\/h2>\n
