Ubercart

I highly doubt it, why would anyone a) want the tutorial in pdf format and much less b) go through the hassle of producing them?
Webpages (made with Drupal ) is the way to go. If you really want the docs in pdf, html2pdf on google gives lots of hits.

Right now the ubercart team is very busy with development on the new 2.x version so haven't been able to put together a lot of formal documentation. The documentation that is available is under the Documentation section in the Navigation section at the right, or is spread throughout the forums. The hard part is to tell if the forum post is relevant to your question based on the sheer amount of changes that are happening in the 2.x version, it makes many posts not much help because even stuff a year old in the forums might not apply to the current ubercart. I have been hoping to find some time to assist in creating some formal documentation to help with the documentation burden for the main developers. Let me know what kind of pdf you are looking for and maybe I can help create one for you.

Thanks,
