I accidentally let 5 or 6 names drop in December (november renewals due), Just stupidity, oversight and not keeping an eye on my renewal dates to blame.
All went through Godaddy auctions totaling over $3,000+ end bids. I debated about paying the recovery costs but with money tight in December and they certainly weren't my best by a long shot. one I still hold the singular for that the plural went for $1,000.
all .coms apart from one .org
Incidently had a confirmed sale at Sedo for $3,600 that same month, cancelled by Sedo after payment due to fraudulent use of a credit card Buyer from Tunisia .(No transfer of domain)
So not a very good month for me either
