When my mom was in college we lived on less than $100 a week ...did it for several years. she graduated in 2005. It really wasn't that difficult, we walked when possible, bought meat when it was marked down, used coupons for essentials such as toothpaste and shampoo usually paying less than 25 cents per product if not free. we didn't use the air conditioner, we kept the heat at around 60 degrees. If the outdoor temp was in the 50's the heat was off. we did splurge on a High Efficency washer, in the end it reduced the water bill, and we hung clothes to dry. we had a pantry that we stocked with canned goods from Aldi's, we also had a small garden that supplied us all summer with tomatoes and year round with herbs. We had basic cable, we had dial up internet, we had cell phones.
