Free flatbread at Jamba Juice
If the store has them, you get to choose between four types: Tomo Artichoko, Four Cheesy, Smokehouse Chicken, or MediterraneYUM. I'll excuse the ridiculous names because it's free! Find a Jamba Juice near you.
Caveats: not valid in Hawaii, or at any Vons, Pavillions, or Safeway stores. Cannot be combined with any other discount.
