Dude - you need to learn to boil some rice & pasta. Not enough carbs even in a foot-long to sustain you if you're riding 2-4 hours per day. My grocery bill in peak training (14+ hrs per week) is still almost always <$30 / week for the foodstuffs, and I eat a LOT. I'd use the footlongs for a "treat", but for the bulk of your foods, go bulk carbs all the way. Cheaper AND healthier.
