When I was s student I used to shop at a place called Waremart. They had huge amounts of bulk food. I would buy a big sack of macaroni sold by the pound and a block of fake Velveeta cheese the size of a cinder block. I would live on that cheap macaroni and cheese for a month for a few dollars. Saved enough to buy a six pack of Mickey's malt liquor each week. Almost died of malnutrition, and to this day can't even look at mac and cheese, but hey it was cheap.
