With participation and available treats varying by zip code, on either January 23 or January 26, select Dairy Queen
locations offer 50% off
during its Customer Appreciation Day
. (After entering your zipcode, you'll see what's available at your local store.) That's the first deal we've seen from Dairy Queen in over a year that hasn't required a club membership, and depending on where you live, it could be the best Peanut Buster Parfait or Dilly Bar deal we've seen.
