Posted on May 1, 2009 Written by Mary Leave a Comment I posted in my local group that Kmart was doubling up to .75 starting Sunday at our Orange City location. Well, I just called Customer Service (1-866-Kmart-4u) and spoke with Mary New info: KMART IS DOUBLING COUPONS UP TO $2 IN VALUE, LIMIT 25 COUPONS!!!! ***I only checked Orange City’s location, however, while searching, she mentioned PORT Orange & Orange Park** (Im guessing she did a search for “orange” lol!!!!
