Walgreens Back to School Coupon Book!

Walgreens has a back to school coupon book located somewhere in the store that has a $1.00 off any (1) Green & Blacks Organic Chocolate product.

I haven't seen this yet, so I don't know if it can be used elsewhere or be stacked with the Mambo Sprouts coupon. These coupons expire 8/29/09. Does anyone have one they could share the info on?

Thanks I heart Wags!
