Rachel Syme, a magazine columnist for the New Yorker, told NPR that she asked several people gathered outside of a Brooklyn second-hand store earlier this month to make donations whether they were motivated by Kondo's show.
"I went down the line of people and just asked them, are you here because of the show?" she told NPR. "Nine out of 10 of them were. They had seen the show and immediately felt moved to get rid of their belongings."
Employees of Goodwill stores across the country have told several news outlets in recent weeks that they've seen an increase in donations, but Goodwill's public relations and multimedia manager Malini Wilkes told CNN that the uptick might not be entirely related to Kondo's show.
“Activity (at our stores) is often strong the first week of January anyway,” Wilkes said. “People have New Year’s resolutions, people have time to get their boxes together, that kind of thing.”
Brendan Hurley, a spokesman for Goodwill of Greater Washington, told "Today" that donations have skyrocketed at stores across the area, but he said it was impossible to say whether Kondo's show was related to the spike.
But not all retailers were uncertain. In Chicago, used bookseller Ravenswood Books said in a Facebook post that the store “took in a month’s worth of books in (two) days” after “Tidying Up” hit Netflix.
