Unilever is offering a free Unilever coupon book when you call this number: 1-866-204-3942. The system is automated and all you have to do is leave your name and mailing address. The book is full of Unilever brand coupons. This is a great way to add to your coupon stash for free! I’m not sure how long this offer will last so don’ wait too long to get yours.
