I just got home from Dairy Queen with my family. We were using our Buy One Get One Free Blizzard coupons! Sign up for the Blizzard Fan Club to get your own coupon!
Also, Jenny told me about the Sonic Birthday Club. Sign your kids up and they'll get a free kids meal on their birthday! My niece just got an email today with another coupon for her half-birtday! And for the older folks, Sign yourself up to be a Sonic Cruiser and you'll receive your own surprise on your birthday!
