Oral B indicator toothbrushes are 2/$4 with a $2 RR this week.
Use the coupon to get 2 for $2 and then use your $2 RR from Carefree (company on the RR is McNeill) to pay for the transaction. You will need one filler item so that you have more items than coupons. The Walgreen's on Barnes in Colorado Springs has pencils in the clearance section for five cents, so you will end up paying tax and .05!
Then, use this $2 RR to purchase the monthly Carefree RR deals. You can find a $1/1 coupon for Carefree here: https://secure.startsampling.com/sm/100830/captureAddress.iphtml?item=100830&source=. Again, you will need a filler item!
