Dairy Queen is running a promo on their Blizzards. Buy one, get one for .99 cents. This offer is valid in Canada as well as the US. DQ is running March 5th until March 25th in Canada.
While I was on the DQ website checking out the deal I noticed you can sign up for the Blizzard Fan Club located at the bottom of the page. They will email you 2 ecoupons (printable coupons). One for a free mini, small, or med. Blizzard, when you buy a med. Blizzard, the other for $3 off an 8″-10″ Blizzard Cake. Click here to go on the DQ website to sign up.
