"Mr. Colvin does not believe he was price gouging. While he charged $20 on Amazon for two bottles of Purell that retail for $1 each..."

"...  he said people forget that his price includes his labor, Amazon’s fees and about $10 in shipping. (Alcohol-based sanitizer is pricey to ship because officials consider it a hazardous material.) Current price-gouging laws 'are not built for today’s day and age,' Mr. Colvin said. 'They’re built for Billy Bob’s gas station doubling the amount he charges for gas during a hurricane.' He added, 'Just because it cost me $2 in the store doesn’t mean it’s not going to cost me $16 to get it to your door.'"

From "He Has 17,000 Bottles of Hand Sanitizer and Nowhere to Sell Them/Amazon cracked down on coronavirus price gouging. Now, while the rest of the world searches, some sellers are holding stockpiles of sanitizer and masks" (NYT).

ADDED: Colvin acquired his stash by taking "a 1,300-mile road trip across Tennessee and into Kentucky, filling a U-Haul truck" with what he found in "little hole-in-the-wall dollar stores in the backwoods." The commenters at the NYT are letting him have it, saying he's clearly much worse than the man he calls "Billy Bob."
