I think benefits are dependent on each state's policy so I would have no idea if you can get more. In the city where I live you can get subsidized housing that costs ~15% of your monthly income. Would you be willing to move to similar to cut costs?

Getting dried beans versus canned beans is more cost efficient. Fresh fruit/vegetables are expensive; bananas are the best buy here. We sometimes go to Little Caesar's pizza when they are closing and if they have pizza left they will sell them for about a $1.
