Is it strictly food or could you get stuff like toilet paper, paper towels, cleaning supplies?

If I won and I had to get all food items--I'd get staples that have a very long shelf life: dried beans, rice, pasta, canned and jarred food, cereals, flour and sugar; and then a few things that we like that I won't buy because it kills me to spend as much as they cost!
