This a unique coupon, one that gives certain (Iphone OR Itouch) users a FREE Starbucks run! Barnes & Noble has a new mobile coupon for anyone willing to download its new Barnes & Noble Bookstore application. The coupon entitles you to a tall brewed, non customized coffee (Boring, yes. But free.) at any Starbucks location inside a B&N. Simply download the application and then show the coupon you receive on your iPhone or iPod to the barista. The application you need to download also comes with some freebies of its own. You’ll get four free e-books plus a copy of Merriam-Webster’s Pocket Dictionary.
