You've heard of flipping houses, but this couple is flipping something else.
Kristen and Juston Herbert are bringing in the cash by buying popular products at low prices and selling them at higher costs — and they're getting rich doing it.
"We'll clear $1 million in sales this year," Kristen told Inside Edition.
The couple say they are reselling dish soap at four times its price at the dollar store. And they say they're getting 10 times as much money for a seasonal autumn air freshener spray they bought at Walmart.
The parents from Arizona are also cleaning up on big-ticket items like a Dyson vacuum cleaner. They bought 23 of them on clearance at Lowe's for $137 each. They plan to resell each one on Amazon for $500.
"There are some days where we walk into a store and literally in 15 minutes find over $1,000 in profit," Juston said.
It's called retail arbitrage and the couple has their own YouTube channel for it, along with dozens of other retail arbitrage fans who post their buying-and-selling sprees.
Here's how they do it: First they search online for items that are popular and trending, like Contigo water bottles. Then they shop for clearance inventory at stores, purchase those products and resell them at a higher price to meet demand. The Herberts say they also buy items that will soon be popular, staying ahead of the curve.
