I purchased it for either $12 or $13 - I forget which. It says so on the cover, but, er, laziness.

I'd say don't buy it for the coupons alone. There are only a handful I'll actually use and there are many that come with pretty specific restrictions. That said, I did use a Heine Bros coupon that was a buy one, get one for a bag of coffee. That one coupon alone nearly paid for the book - I got an $11 bag of coffee for free (well, with purchase of the coupon book - but you know what I mean). There are coupons for Whole Foods, Rainbow Blossom, and Valu Market, if you shop at any of those places. All of those coupons have restrictions, though. If you're buying it for the coupons, I'd flip through it first.
The book also includes a recipes section. I've flipped through it and lots of them look pretty tasty - we'll be trying some of them in the next few weeks. Many are seasonal, so it'll be good to have around as local produce changes with the seasons.
