Sun Mart currently has these boxes of Betty Crocker Mac and Cheese marked down to just 50-cents! Combine this amazing sale price with a 25-cent coupon found on coupons.com that will make them 25-cents.
I previously reported these to be free but Sun Mart will not double internet coupons.
UPDATE 9/10: I went back to Sun Mart today and used my two 25-cent coupons and they did in fact double despite their policy saying they do not double internet coupons! Both boxes were free after coupons!!!
