In honor of Valentine's Day, Walgreens is offering a set of photos and enlargements for free, one per customer. The set includes 1 8x10, 2 5x7, and 4 4x6 photos. I'm not sure yet if all the pictures must be the same (in the example provided, they are).
To get the discount, go to the Walgreens website and order using the coupon code VALENTINE. Orders must be placed and picked up between Februrary 7-9.
