Walgreens is offering a free 20-page photo book for a very limited time when you use the coupon code 'FOREVER.' As with many of these free photo offers that come about online, you will have to pay a few dollars for shipping (about $2.99). The deal is only good through tomorrow. Choose the Purse Books in the Photo Book section, design yours, then enter the code at checkout. As always, check to be sure that the full amount of the purchase price has been removed from total before you submit.
