Garage sale for gas money. It reduces the amount of stuff you're carrying and adds to that dime in your pocket. Garage sales are huge over here, there's not much you can sell over there that can't be replaced over here.
It also depends on what you drive. There's not much you can carry on a Geo Metro across country, but if you're driving a 1977 Malibu Classic (old land yacht) you could potentially carry quite a bit. Granted you couldn't take any furniture and you'd look like you were living out of your car, but hey it's for pharmacy school, right.😉
