How can I order this book thats taken me many many days and hours to make??

I think it depends on location. I believe Shutterfly is one partner in the US but it does change occasionally and some regions may not have an Adobe partner. Home printing may be the only option unless you export the book as jpeg, tiff or PDF.

You do that by opening the saved book project and from the menu bar choose:

File >> Export Photobook

Choose your preferred format e.g. jpeg and click the browse button to select a folder to save them to.

Each page with its background, and photo layouts will be exported as a separate jpeg. You may then be able to send those jpeg files to a local print lab, or upload them to an on-line book website.
