This book has a ton of great coupon from Proctor & Gamble!
The offer is available again, even if you received one this last time!
One of the coupons in the booklet is for a FREE bottle of Cascade Jet Rinse (I believe that's what it's called)!
Other coupons include Swiffer, other Cascade items, and basically household cleaning product coupons!
