My offer is $10 each to take them off of your hands. That is what I believe the value to be. You must pay me. If you get offers above zero dollars from a legitimate bidder then I will reconsider.
The "don't know what the traffic is" line is pretty old at this point. The traffic is zero. If someone pays you money for these then give me their contact info and I'll throw you a bone.
If you pay me $10 each I have to check my PayPal and see if the money is there, and then I have to add these names to my list. I then have to change the Nameservers. Why would I do this for free with these names?
