Iconic TV actress Melissa Joan Hart and Heroes star Greg Grunberg called the Get Up & Go Show this morning to chat about their new mobile coupon app Yowza! Its a free app for both iPhone and Android users that displays mobile coupons to be redeemed at retailers in your immediate area.  Melissa, a mother of three boys, can't live without it and one of her partners in the app, Greg, says its very user friendly.  **note Melissa is partnered with both Greg Grunberg (Client List) and comedian Wayne Brady (The Price is Right).

Find out what they have planned for the New Year and what Melissa Joan Hart is working on for next September.  Follow both Melissa and Greg on Twitter for more details.
