Where are good places online to purchase used textbooks?

bigwords.com

Or use the reserve copies at the library. I purchased very few of my textbooks as an undergrad.

half.com

I found this website with a google search
http://www.textbookx.com/
it looks to be pretty useful, hope it helps!

I asked this a LONG time ago

Look into Facebook’s Marketplace, you might just find your book being sold.

Thanks Nikipedia’s answer saved me over $300!!!

I’m lucky because my school doesn’t have a real bookstore (we’re in the middle of NYC), and we just bu our textbooks out of the local Barnes and Noble, where you can also sell your books back. You might check and see if your school will buy your old books back or if it has a used book system; most colleges have one.

Yeah our bookstore is actually a barnes and noble and we can sell back our books, but I didn’t get much back.
