Do your homework before shoping here.
I had high hopes when I first heard of them my first semester of school. Yet after the first two times I went there I've noticed a major change in staff and the way the place is run and its gone down hill. The biggest suggest I could give is going to the schools bookstore or website and finding your books there first so YOU know what your looking for. Time and time again I see people being sold the wrong book because they don't have great access to the schools database of what the the teachers are using ... i.e.last semesters book when ur class is using the new edition of the textbook or buying what most of the teachers are using when your teacher uses a self put together work book only available at the bookstore.
They do have much better prices and a lot more used selection than the school. I bought the access code for my 350 math class here for at least $20-25 cheaper here than the schools store and you avoid shipping costs that you would get using online sources like amazon.
