I got the Scrubbing Bubbles One Step Cleaner (box with the yellow stripe on it only) I was able to score 6 of these at my Walgreen's. They were $4.29 a piece. I used (6) $4 off coupons I got for being a Buzz Agent. I personally like them. They do not keep your bowl spotless however, you do still have to clean it but just not as often. So my cost was $1.74 plus tax. Sweet! I'm in Minnesota in case anyone was wondering. These were not marked on the shelf, I had to ask for a price check. They also have (2) $3 off coupons for starter kit and (1) BOGO coupon for the refill canisters inside the box. I have heard not all regions carry these.
There are a few different high value coupons out there right now, so it may be worth a look.
