In a special "Clean Sweep" cleaning supply ad at HyVee (can view online), Formula 409 and Clorox cleaner are $2.50 each. Plus when you buy 2, you can save $1 with a HyVee in-ad coupon making each bottle $2. This ad is good through 4/24/13.
Head on over here quick (before prints are gone) and watch a short video and share to be able to print a manufacturer coupon good for $1.50 off per bottle! Stack the in-ad coupon and this coupon and get each bottle for just $.50 each!
If you choose not to share, you can still grab a $1 off coupon. Still a nice deal at $1 per bottle!
There is also a $1/2 Formula 409 coupon here.
