I LOVE these kinds of deals! Basically, any time between 10/21 and 11/13, you can earn a $10 Old Navy cash credit for every $20 you spend. You are allowed to earn a maximum of $30 “Super CASH” per transaction ($60 or more purchase required).
Redeem you Super CASH between 11/17 and 11/22. That’s the time that you USE your $10 credit for every $20 you spend.
