It completely depends on the domain name. If it's a fresh registration then you wouldn't expect to pay more than the standard $10 figure to register it. If it's not a fresh registration then the amount I would pay would depend completely upon things such as traffic, domain name brandability and any page rank it may have already existing.
Hi, Prices totally varies domain by domain so their is no fix price for that. Every company have their own discounts & coupons. Currently Godaddy is offering .com domains @ just 109 in India through their PPC campaigns and on through their site they are offering .com @499.
I bought the cheapest .com domain from Godaddy at $0.99 and i think it's a great deal. Register.com is offering $0.50 domain but i didn't buy any domain there since there's too many scam reports i've found over then internet regarding their services. We want quality and affordable website to buy domains and not just a cheap one.
With the market price , it should be not more than USD 10 . But people now getting smart where they won't look on the 1st registration fees but look for renewal price as well .
