I havent thought of mac n cheese
but we did get parmesan cheese the big one it was 5.38 or something like that. We looked at velveeta but it was 3.50 and 4.50 so we passed it up although if you went with velveeta and a bag of cheese thats 5.50 so .50 for the two. 2 bags of polly o string cheese is 5.36 so .36 for 2 bags of string cheese. I used a total of 4 in one transaction no problems either.
