So... as we already know, there can only be one of any domain name that is registered, we also know that there are "drop catching services" or back orders, that customers can put on domains to pick them up as soon as they are available to the general public. services like that can be used for good just as well as they can be used for bad. I used to work as a universal support agent for network solutions, and i have heard stories like this more times than not... unfortunately the only opportunity that exists in the situation at hand is to add it to your watch list and catch that baby as soon as it drops! Just be patient, and remember good things come to those who wait.
From what I understand, premium domains are domain names that have already been registered and are being sold at a "premium price." The only way around it is to pay the price of the domain.
