If you suffer from cold sores than you know how miserable they can be. I don’t get them very often (thankfully) but when I do I’d pay anything to make it feel better. Polysporin Canada has a free printable coupon available on their website. Save $5 on the purchase of Polysporin cold sore healing patch. It actively heals the cold sore. It states that it instantly hides the cold sore as well but Im not sure if it actually does. I have never used these patches. If you have used them please provide us with some feed back!
