Edgar Dworsky has become the go-to expert on “shrinkflation,” when products or packaging are manipulated so people get less for their money.

Clare Toeniskoetter:

Lately, Mr. Dworsky has had his work cut out for him. With inflation at a 40-year high, business owners have been increasingly shrinkflating their products in an attempt to hide price increases.

Companies are doing it out of necessity, said Krishnakumar Davey, president of consumer product goods at IRI, a market research company. “Manufacturers are facing huge costs,” he said, referring to the price of raw ingredients, labor and shipping. “They’re trying to figure out how to balance that.”

Mr. Dworsky works seven days a week from his modest, three-bedroom condo in Somerville, where he lives alone. But for him, thrift is more than a job, it’s a lifestyle. He made less than $7,000 last year, mostly from donations and ad revenue. He gets by on Social Security, his state pension and savings.

He’s quick with one-line zingers about his own frugality: I preach what I practice. Splurge isn’t a word in my vocabulary. People go duck hunting or deer hunting. I’m bargain hunting!
