Not going to be using credit cards for school, and related expenses in the coming school year. So, cash it is and I have no idea how much is an ok allowance. I will also have to be responsible for gas (for car). I usually bring healthier food option for lunch, prepare my own coffee that I put in a mug during the morning (so no Starbucks run for the most part), and don't go out a lot except on sporadic times that i'm invited by classmates/friends. How much would be an ideal cash allowance/day and not have to worry about having no cash left at the end of the day?
