You got anything worth anything? Im sure you got a pawn shop or a cash convertors somewhere.. They only give you about 20-25% of what a item is worth brand new, but if your in a tight spot you might be able to find some stuff to get rid of.. Old game systems, dvds, baseball cards, jewelry.. They even take garden equipment and shit like that..
Or you could hustle real quick.. take ya 15 bucks and find someone to spot you a eight or quarter and tell em you'll give em the rest back later if your real cool with em. If you get rid of it quick you'll make like 30+ bucks profit..
