Prefer Crest toothpaste and Oral-B toothbrushes?

I’ve done this Crest deal twice now, once with manual toothbrushes and today with toothpaste.  The manual toothbrushes were tagged Buy 3 get $5 in Register Rewards (the screen shows $4 W Cash); I bought four (one a clearance duo for only 80¢) and received a $4 RR.  In this transaction I had the screen shot (there were no tags on any shelves) showing the deal.  Bought two and received a $4 Register Reward.  Again, nowhere near as valuable as W Cash.  Each time I was told to keep the RR and had bonus points added to my account.  I like the bonus, but really wish Walgreens corporate would travel back to 2011 🙂
