On March 1, the day after the first coronavirus death was announced, Matt and Noah Colvin started a three-day, 1,300-mile journey from their homes in Chattanooga, Tenn., filling up a U-Haul truck with hand sanitizer and antibacterial wipes. Then Amazon cracked down on price gouging.

“It’s been a huge amount of whiplash,” [Matt Colvin] said. “From being in a situation where what I’ve got coming and going could potentially put my family in a really good place financially to ‘What the heck am I going to do with all of this?’”….

Mr. Colvin said he was simply fixing “inefficiencies in the marketplace.” Some areas of the country need these products more than others, and he’s helping send the supply toward the demand.

“There’s a crushing overwhelming demand in certain cities right now,” he said. “The Dollar General in the middle of nowhere outside of Lexington, Ky., doesn’t have that.”

He thought about it more. “I honestly feel like it’s a public service,” he added. “I’m being paid for my public service.”
