I discovered Booking.com when I was planning our anniversary trip to Canada last month, and booked 3 of our lodging destinations through this site. Imagine my surprise when, upon our return, Booking.com sent me a link for a free photo book from Mixbook! It was very easy to create on their site, they shipped it in a timely manner, and we received it today. In addition, the site allowed me to publish an online version to share, (with the option to make it public or to only people with the link). Check it out here!
