Proctor & Gamble offers a selection of free coupons and samples when you register for a P&G everyday account. That's the best offer we've seen from Proctor & Gamble. (It offered a free coupon book with up to $25 in savings in June.) Among the samples are Pampers wipes, Crest toothpaste, Oral-B floss, and more. Allow four to six weeks for delivery.
