What is best affordable source to get TEXTBOOKS?

I am looking to get(Title: “Everything’s An Argument” 7th edition Author: Andrea Lunsford and John J. Ruszkiewicz)… I reviewed this form for posting,

http://www.collegeconfidential.com/admit/five-ways-to-save-money-on-college-textbooks/

I am not able to find pointers for downloading textbooks sites or renting options.

I did check half.com, but this title is not coming up.

We are not able to find a rental/used book for this title in book store. Even we buy it, it become obsolete at end of semester . There will be another edition in Jan 2017, so no re-sale value for it.

The school library does not have it.

What are the sites for renting/downloading College Textbooks?

Thanks for your guidance.

What is the ISBN? In the meantime, try Chegg.com.

Thanks. Here is the ISBN-13: 978-1457698675, ISBN-10: 1457698676 . I find Amazon looks good. Any other better than Amazon. I did find eznotes.forumchitchat.com has free download. The link take it long survey and at the end. I did not get the download. Any success with this site?

I hope this helps.
