Mark Cuban Thinks You Should Buy a 2-Year Supply of Toothpaste. Here's Why

Mark Cuban is the owner of the Dallas Mavericks and is well-known for his business skills and investing prowess. Over the years, he has provided some tips to others who want to get rich, and one of them was a pretty surprising one.

His advice: Buy a two-year supply of toothpaste. Here's why the billionaire suggested making this unconventional move.

Cuban has a simple reason for buying so much toothpaste

Mark Cuban doesn't just want your teeth to be really clean. He had a good reason for suggesting purchasing such a large stockpile. Specifically, he advised doing this if you use the same brand of toothpaste regularly and can find it at a deep discount.

"If we, hopefully we're all using toothpaste every day, right, couple times a day, and we're gonna go through toothpaste every month, whatever it may be, you're better off buying two years' worth of toothpaste when it's on 50% discount," he said. "That's an immediate return on your money."

Cuban's point was that the prices of items go up over time, so you're better off purchasing them at the lowest possible price as this puts guaranteed money in your pocket. You also immediately benefit from the savings since you get to spend less now and in the coming years, keeping more cash in your bank account.

Toothpaste isn't the only item Cuban believes you should stock up on. "Any of your reusables, consumables that you have to have, when they're on a huge sale on Amazon, buy them, because chances are, their prices are gonna go up, but that's a real savings that you get to put in your pocket."

Cuban said that while it can feel difficult to make a profit by investing in a brokerage account, this is a simple step that anyone can take that will have an immediate positive impact on their personal finances.

Should you follow Cuban's advice?

Listening to Cuban just makes good sense -- especially as the recent few years of rising prices and surging inflation have demonstrated that routine products and services that we use every day can and do see big price increases.

If you're able to get many of your consumer products at discounted prices, this can make a noticeable difference in your personal finances. It's not difficult to do either. Most stores put items on sale on a predictable schedule, such as marking down a product once every six or eight weeks. If you can stock up when there's a good price -- and especially if there's a deep discount, then you'll be able to slash what you spend on groceries and personal care.

Use this extra money wisely to do things like repay debt or invest for your future, and you will end up being able to build wealth without changing your lifestyle at all. But, no matter what you do with the money, you probably have better stuff to spend it on than paying full price for toothpaste.
