If the site I'm looking at is a guaranteed dead end to today's research, then my only option is to look elsewhere.<p>Whether I fill in the sales form or go to another site, there's no way I'm going to get the information I need immediately.  As a result, going elsewhere saves me time, while filling in forms in the hope somebody replies is a waste.<p>Add in a history of bad experiences with companies using similar sales processes, and it's nearly 100% that I'll leave and never come back.
