When I started college I had like $1500 in startup money (was living in an apartment since the school I went to didn't have dorms). When I got there, the water pump went out in my car like the first day I was there and cost $600 to fix, and the first/last month's rent pretty much ate up the rest of it so I was broke as fuck until I could get a job and that took me like 6 weeks to do. My roommate and I went to the grocery store and the store-brand mac and cheese was on clearance for 8 boxes for a dollar. I bought two cases of 48 boxes for $12 and lived on nothing but store-brand box mac and cheese for a month. One box for lunch, one for dinner. I didn't have milk or butter so it was just noodles and cheese powder. I had like 24 boxes left when I finally got my first paycheck and I threw them all in the trash. It was a good 2 years before I could stand the sight of any mac and cheese and 5 years before I would even consider the powdered cheese stuff. Now though, even I can appreciate the occasional shitty box mac and cheese, but only Kraft, no store brand.
Definitely going to try the chemistry mac and cheese though.
