<prompt> Human: So Im currently finishing up my last semesters of schooling and I work a part time job for 12 an hour. This is enough to get me by in terms of bills.

I can comfortably gather 150 dollars extra per month, but I would like to know what other options I can follow.  <response>: Save up and pay with cash.
