Shop at Home. They are simply a mediator between you and your desired online merchant. So, instead of going straight to the Entertainment Book website, you go to Shop at Home's website and let them bring you to Entertainment Book in exchange for 45% cash back. That is worth it, in my opinion!! :)
There's a great deal right now and it won't last long. The 2011 Entertainment Book is on sale for $17 with free shipping PLUS go through Shop at Home and get 45% cash back! If you are a new member to Shop at Home, you will get $5 just for signing up. Let me know if you need help. :)
If you prefer to use Ebates, they are offering 17.5% cash back and you also get $5 if you are a new customer.
