Entertainment.com has their coupon books for $10 with free shipping.
Ebates is running 17.5% cash back on Entertainment.com.
So using the Ebates site and buying a book you can get it for $8.25 total after the cash back.
The Entertainment.com site says its a "flash sale" so I don't know how long it will last.
I can't vouch for the quality of the coupon books nowadays and its going to depend on your local market and what you want as far as coupons. Last time we bought a book we didn't use it but you may get better value out of it.
Standard Ebates blurb: To get cash back from Ebates you need to be signed up with Ebates. Then simply go to Ebates to get the referral to the store before you do your shopping. I also get a referral bonus if you use my links to sign up with Ebates.
--This article does contain referral links which will hopefully pay this site a big commission for purchases made at the sites.
