These are often on sale for $1, making them $0.50 each after the coupon. We actually use the shampoo as hand soap in our liquid hand soap pumps. At $0.50 per bottle it's less expensive per ounce than any other hand soap I'm usually able to get with coupons. A reader gave me this tip a number of months back and it really does work!

$1/1 Wheat Thins (Thanks, Karin!)
