Sign up for Kno.com through this link and you’ll get a unique code to get $5 off any purchase at Kno.com!
BUT, it gets even better because you can use the code “KNO4PARENTS” to get up to $10 off any K-12 eTexbook purchase and pretty much all of their books are less than $10 so you’ll get a 12 month rental for FREE!
I tested it out just now and this was my sample order (although I think I’m going to go get the Writing book instead):
Then, once you sign up, you can get a link to refer your friends and get $5 for every 5 friends you refer! And, of course, the link in this post is my referral link because that would just be amazingly awesome to get some $5 credits. 🙂
