It also means that the price isn't fixed, and that a good negotiator might be able to get a lower price than someone else. The whole "call us" also typically lowers the noise on the vendor's end as well. Anyone willing to take time out to contact them would be a much better chance of closing a sale. They are what would be known as the "good leads". If you're a user and researching multiple vendors with similar services/products/apps that have decent $$$ attached, you'd be a fool to not contact and only pay the price on the tin.
