Pizza X has the best food deals and stay checked in on Eat Cheap Week to try what Bloom has to offer for little money. If you are interested in spending little and staying small, split something with a friend. Many clubs and organizations on campus provide free food, drinks, and deserts for showing up to discussions, resource help functions, and meetings. Even if you are only interested in making a organization appearance for the food, do it! More than likely the food is being provided so that you will come and you might see an interest develop. The Urban Outtfitters on Kirkwood has very very good sells so check that out. College Mall isn't very grand, but they have good deals as well.
