I just got an offer for 300$. Its worth 5 times more then that. I paid for a domainvalue at Sedo to a similar .pro name and that name was worth 3500€ (euro).
I recently sold texasholdem.pro for 4000$
The only reason Im selling this one is that I aint got any time to develop a site for it.
The highest bid will get the domain, in 72 hours. Bids over 400$ will get it at once.
Cheers
