for me I test my domain first via out bound, if one of CEO reply with how much, usually I will give price about $3k to $15k! even the deal off with that CEO, I don't really care that much! because once CEO said, how much! it mean that domain have value! ,
but if my outbound test failed! I will give the domain name as low as $250

or let it expired!, because if CEO don't have any interest with my domain, for sure! my domain suck so bad

but if one of them reply with how much! its good indication, even the deal is off, and that CEO hoping $100 domain!
but if my domain never outbound, and often get offer, I will give the price , min offer mid XXXX=4k to low XX,xxx,
what if no one buy ? at least we know the price suck!

but don't let that kind of domain expired!
