Karyn E. Bosnak (born September 24, 1974) is an American author of two published books: Save Karyn and 20 Times a Lady.
Karyn Bosnak was born in Chicago, Illinois. After briefly attending the University of Illinois at Urbana–Champaign, she received a Bachelor of Arts degree from Columbia College Chicago in 1996. She currently resides in the Brooklyn neighborhood of Cobble Hill.
After spending much of her early career as a daytime television talk-show producer, Bosnak moved from Chicago to New York in 2000. After quickly running up $20,000 of shopping-induced credit card debt, Bosnak lost her job and found herself unable to pay it back. In June 2002, she started savekaryn.com, a humorous albeit controversial website on which she brazenly asked strangers to help pay it off. The website garnered international media attention and worked; Bosnak paid off her debt in twenty weeks.
In 2003, Bosnak chronicled her struggles with debt in the memoir Save Karyn: One Shopaholic's Journey to Debt and Back. It was published in the United States by HarperCollins and is now available in over ten languages around the world.
