Right now you can get TWO Entertainment coupon books for just $10. Standard shipping charge is just $1. Plus if you use Ebates to make the purchase you can get 17.5% cash back. That would put your cost at about $9 total after the cash back or $4.50 per book. You can get one book from your home town and a 2nd book for another town of your choice or get a book for a friend.
If you aren't familiar with Entertainment coupon books then you should first check out their website to see if they have deals that you'd actually get value out of. This year the 2011 book wasn't that great of a value for us and we've not really used it unfortunately. But in past years they had at least one coupon that I could use for $20 at a particular restaurant so it was a great deal.
To get the 17.5% cash back you need to be signed up with Ebates. Then simply go to Ebates to get the referral to the Entertainment site before you do your shopping. I also get a referral bonus if you use my links to sign up with Ebates.
