Why not try the "$5.00 Foot Long" at Subway every day?? Different Sub every day of the week. Have 'em pack on the "extras" a little heavy. That's about $40 for 7 days. (taxes) use the other $10 for a big bag of generic chips and case of Walmart brand sodas. Eat half for lunch and the other half for supper.
You'll make it just fine................
I'd be at the side of the road by Wednesday
