"No matter what your financial situation is, there's no reason not to use coupons. It's like free money in your pocket!" Gosselin said in a statement. "I'm thrilled to lend my expertise to CouponCabin.com where you can easily find the best deals on practically everything."
Gosselin, the single mother of eight young children, will contribute a weekly post on topics such as how to stretch a budget for a large family, holiday shopping tips, gift ideas and more. She will also be sharing coupons from CouponCabin.com on her own blog at www.kateplusmy8.com.
"Kate has embraced coupons her entire life," said Jackie Warrick, president at CouponCabin.com. "We look forward to sharing the unique insight she has gained over the years."
Gosselin's first blog is to run Nov. 22.
She was the star of the TLC shows "Jon & Kate Plus 8" and "Kate Plus 8," as well as a contestant on "Dancing with the Stars."
