how much to sell in godaddy auctions?



Flippa is primarily a site for selling websites, with domain. But, there is no shortage of domains being listed as standalone entities, and many achieve a half-decent price. Keyword rich domains tend to do better than brandable domains, although if you are selling something with page rank then you should do OK. Flippa is a good option for a quick sale.
 
I agree with inforayssan, do not list it on Godaddy but list it on Flippa. Many successful Internet Marketers use Flippa instead of Godaddy. This is because godaddy is mostly used for buying domains and Flippa is mostly used for Buying a website (as in whole)
