Aye, those domains are not $1666 each. I mean, I'm selling off things like asow.com, easyborrowing.com, rentme.co.uk, q29.com, yourhd.tv etc. for $500-$1000.
I'm even selling off bulk domains like those for $100 each. I've been selling domains for 12 years now. The time for $$$s sales is over. You'll see the average sale price of domains drop year after year now.
You might as well sell them off for low prices now to people that can use them and want them ... or still be holding them in 10 years time having spent $$$s in renewal registration fees.
