I love all of my photos even tho I couldn't purchase all of them at the moment but they're beautiful...I just wished it was a way for you to pay for the extras anytime not only that one time ..Is it a way that you can purchase them online and have them mailed to you? And I wished I could've took a pic of the others I couldn't purchase with my phone to have for my grandson...
