Free Shipping over $50

CONTACTED CUSTOMER SERVICE, SPOKE WITH CAROL ON THURSDAY 3-8-2012. QUESTIONED HER ABOUT THE FREE SHIPPING ON $50. THE SHIPPING WAS NOT DEDUCTED FROM MY ORDER AS TWO OF "SHOP AT HOME" COUPONS NOTED. CAROL INFORMED ME IT WAS $60 FOR FREE SHIPPING. WHY IS THE $50 FREE SHIPPING STILL LISTED SINCE IT WAS HONORED AND I RECIEVED CONFIRMATION THAT IT WAS. USUALLY WHEN A COUPON IS NO LONGER AVAILABLE IT HAS A EXPIRE DATE OR NOTATION WHEN TRIED TO BE APPLIED. IS THERE ANY REASON WHY THIS CANNOT BE HONORED? IF A DEPARTMENT STORE HAS AN INCORRECT PRICE ON A ITEM THEY HONOR IT. WHAT IS UP WITH YOU ALL NOT HONORING A COUPON THAT IS NOT EXPIRED?????? I WILL GO AHEAD TO PURCHASE ANOTHER ITEM TO MEET THE $60 LIMIT; HOWEVER, I STRONGLY BELIEVE YOU NEED TO HONOR WHAT IS PRINTED.
