From the Dairy Queen Facebook page:
That's right, we're bringing the party to every participating DQ in the US and Canada*, and throwing a BOGO Blizzard your way for $0.25. No coupons. No memberships. Just because you are the best fans in the world, and we want you to celebrate the Blizzard's 25th Birthday too!
If you can't wait till April 19th, you can score a Blizzard BOGO coupon when you join the Blizzard Fan Club (coupon usually comes 24-48 hours after signing up). Either way, we hope you'll celebrate the Blizzard's 25th Birthday with your friends and family at your local DQ!
We've got so many fun things planned for you this year, so stay tuned and thank you for being the best fans in the world!
*For a limited time only at participating locations. Valid in the U.S. and Canada only. Offer applies to regular price Blizzard® treats of equal or lesser size.
