There is a new high value $2/1 Scrubbing Bubbles printable coupon available from the manufacturer. This coupon is good for $2 off Bathroom Cleaner with Color Power Technology. There is also a $1/1 Target printable coupon available you can stack with this one to get $3 off this product at Target. Look under Household to find this Target coupon faster.
My guess is that this product sells for around $3.99 or so. So stacking these Scrubbing Bubbles printable coupons would get you 75% of or so.
