I have numerous domains (from years ago) with a very well known and expensive registrar that are up for renewal. I was unlocking them to make a transfer and a message reads " if you are unlocking to change providers we will do whatever it takes to keep you."
Hmmm. These folks are twice what I pay now from a likewise credible and well-known provider. Do you think they will drop their price to match the other? I've never really thought about it, but are numerous registrations negotiated?
