I'm a nitwit. Went to CVS to try this deal but I didn't take my phone. I saw the 3/$9 display and talked myself out of it because I know there's a "Buy 3, get 2 free" deal around Superbowl time at the supermarkets. I forgot this is an over outing deal and couldn't bring up this read to see why I went there, lol.
Update: went back yesterday and bought the sale soda with the coupons, but the manager overrode the coupon price saying it had to be the actual retail price, not the price it rang up at initially. Ah well, live and learn. Should have held out for the Superbowl sales.
