@Altronics Onion products are community supported, if you think you can make improvements to the documentation you can initiate a pull request and submit your proposed changes, in my own experience Onion are very receptive to improvements.
I'm not sure which support link you are referring to, could you be more specific so the Onion team is able to address any broken links.
Here in Oz you can order Onion products through Core Electronics who are based in Newcastle (NSW), I also order through Mouser who ship out of Singapore, or Digikey who ship out of the Colorado.
You can check the support system at onion.freshdesk.com where the FAQ directs bulk order enquiries to sales@onion.io
