If you usually buy Listerine whitening quick dissolving strips, print and present this coupon in-store when you next make your purchase. It will entitle you to a $3 discount on this item.
There’s a bit of a description over at The Globe And Mail, if you’ve never heard of these. Apparently, they dissolve after 10 minutes, and you can see a difference after 2 weeks, if they’re used daily.
I’ve never used these before. Have you? What are they like? Are they effective?
Thank you for the picture forevermoosed!
