Blizzard Treats at Dairy Queen - Buy One Get One for 25 Cents

This week is Blizzard week at Dairy Queen!  All week long you can buy one Blizzard treat and get a second one of equal or lesser value for only $.25!

I was feeling nice last week and brought my kids to DQ for a treat and spent a small fortune!  UGH!  Can I get my money back?  Please?
