I used one $1 off coupon for colgate total, two $1 coupons for the Colgate mouthwash (that I printed via coupons.com) and one $2 off a purchase of $6 worth of mouth wash store coupon from previous trip. Also used $5 extra bucks from previous trip. Paid $1.08 got $6 in extra bucks. Total cost: .08 cents for all three. I also I went thru inbox dollars to print the coupons from coupons.com (you get .10 for every coupon you print and use) so technically it was a .22 cent money maker.
