50% off Kellogg's

Just a note that there is 50% off Kellogg's cereal at the Piggly Wiggly March 7,8 and 9 only with additional coupons towards money for future purchases with x number of boxes purchased. I thought I might have heard about another cereal sale this week but I think it may have been out of our area - if anyone knows of one, please let me know - THANKS! Vivian
