It is possible to find a CVS promo code on sites such as Retail Menot or Coupon Cabin, although these discounts often turn out invalid. If the user wants to use this coupon to save on their passport photos and cannot find a valid promo code, it would be best to use an app such as Passport Photo Online, which allows you to get a set of passport photos completely free, from home, with a host of benefits and go to CVS to print your template for as little as 23¢.
