[quote name='darthbudge']I am gonna buy a lot of my books online, but there are two of them that I need by the end of the week and I don't have any money to buy them with, but the bookstore will give me a book loan thingy.[/QUOTE]
A lot of universities will let you buy books and return them in . Keep your receipt, be careful with the book, and in the meantime, try to scrounge up the cash to buy them on half and return the original books to the bookstore for a refund. This way you have what you need until you can get your cheap copy off the interwebs.
