Request your coupon book with over $27 in cleaning product savings plus a coupon for FREE Cascade Rinse Aid. It looks like Procter & Gamble offers this coupon booklet quarterly, so you can certainly request it again because the coupon expiration dates change. The coupons in the last coupon book expired 9/30/08 and I used my FREE Cascade Rinse Aid coupon at Target where it was priced at $3.24. Thanks goes to Frugal, Freebies and Deals for telling me about this new offer! Since it takes 6 to 8 weeks to receive your coupon book, my best guess is that the coupons inside will expire 12/31/08.
Update 9/26/08: I was wrong, the coupons I got expire 3/31/09. And yes, the free Cascade Rinse Aid coupon is included! Still available to request.
