In the early days of photography, people often ate their own pictures, thinking it was the only way to preserve the memories robbed by the camera. Put pics to better use with today's Groupon: for $10, you get a 9"x7" custom-printed hardcover photo book (a $24.95 value) or a 12-month premium calendar (a $23.49 value) from Lulu.com.Photo books allow customers to creatively integrate their pictures into a wide array of projects, whether chronicling a vacation or crafting a custom cookbook. Fill a 9''x7'' hardcover book (20 pages, $0.50 for each additional page) with photographs of best friends and people you met once to create a tangible incarnation of Facebook. Customers with limited coffee-table real estate but ample wall space can skip the photo book in favor of a hangable photo calendar. Infuse each month with a personal touch with a 12-month premium 13.5''x19'' calendar ($1 for each additional month).
