printable showed up this afternoon. 
Pair it with a BOGO sale at CVS or Walgreens to get 2 packs for free!
This $2.00 off any two (2) REACH Toothbrushes has been out for a few days but is still available.
Walgreens frequently runs the Reach toothbrushes 2/$5, get a $3 RR, so I’d save this Q for just such a sale to come along.
