To celebrate the 25th anniversary of the DQ Blizzard you can get one for just $0.25 when you buy one at regular price. No coupon is required. Offer valid 4/19-4/25. My oldest daughter just enjoyed an Oreo CheeseQuake Blizzard this weekend and said it was AMAZING!…I got one tiny bite, so maybe we’ll have to go back this week so I can actually taste one!
