An even better choice for those of you who go to a brick and mortar university... if you have time of course
Once you're done with your textbook.. the following semester look up the exact same course you took and find out on the first day if they will be using your specific textbook. You can always call the college bookstore ahead of the first day and pretend you're in the class (give specific section number) and you want to know what book you need to buy and how much it will cost so you can bring the correct amount of bucks to buy. You can practice your actor/actress skills on this one
When the first day of class comes along.. be sure to be there at the end of class and physically show off your book and hike up your asking price (ex. if the book is 50 new 45 used.. you would probably sell it for 40 online so push 42 etc...).. that way you dont spend on auctions, you don't have to worry about missed payments and best of all... cold hard cashola !
Enjoy!
