Yes, my point was about the expense and ubiquity. Certainly during Imperial times it would have been more difficult, but not to the extent the old WEG sourcebooks portrayed. It would have been the backbone of commerce, just as it is in the real world, but something the WEG writers would never have foreseen.
The WEG writers have corporations (as well as universities and other organizations) using FTL communications regularly. Under the rule of the Empire, they pay for time on the HoloNet and/or cheaper options depending on need. However, Star Wars does NOT have online commerce like we do today. You don't sit on Tatooine and place an order through Amazon Galactic and have your product delivered to your doorstep from a warehouse in Ord Mantell, you can't do comparative shopping across the various galactic marketplaces, and you don't have the option of getting customer service on the line whenever you want.
