Welcome to Domain Social, a domain forum where people sell domains and buy domains, talk about domain name registration and help others when buying and selling domains.
Maybe try googling "What is a Premium Domain?" ??? Everybody from this forum is gone, taking an extra long holiday weekend because we make so freakin much money from selling our domains!!!!
Seriously though, i have googled 'premium domains' so have an idea what one is, what i dont understand is
a) Why it is like $500
b) Is it worth $500, and reliable sources to get this valued pre purchase - im wary of these free apraisals as i suspect they may review all the searches done on the site and pinch some (i did do one on a similar topic which i new would be registered and the value was 80-120k, is this even remotely realistic?)
b2) if i was to pay for the apraisal, do i have any protection of some from there purchasing it instead of apraising it...
