The Entertainment Book is worth every penny you pay! There are hundreds of coupons that will save you more than you spend. Most are B1G1F type coupons, but there are others as well. I also pick one up for areas that we visit (vacations). It saved us $1000+ when we went to Hawaii.
For those of you who live near a Price Chopper, there is usually Price Chopper coupons included.
Right now it is on sale for $7 off with free shipping. If you go through Mr. Rebates then you will get 30% back in your Mr. Rebates account. That makes the Kansas City Book only $19.60 shipped! The prices of the books vary based on your area.
