This week at CVS, there is a regional ExtraBucks promotion on CVS oral care. This was not in the paper ad but a nice surprise online. There are many items included, and if depending on what you buy, possibly get $10.00 worth of oral care for free!
When you view the included products on myweeklyad under the $10.00 ExtraBucks promo (check in "personal care"), you'll see that prices start at $0.99, and the dental flossers are included. Grab four packs of dental flossers for free after ExtraBucks! Keep in mind this likely will not be tagged in your store (luckily, it was at mine)! To be sure it's included in your area, log in and view your personalized ad at myweeklyad at cvs.com and also view other included items.
There are many different products included in this promotion. You could also try the two-pack pulsating toothbrush or overnight denture cleaner.
