I just recently changed my domain registar from Dotster.com to GoDaddy.com.  I did this mainly because Dotster started to charge for the DNS manager...$10 per year.  During the transfer, I got this email from Dotster:

We’d like to encourage you to stay by offering you reduced account pricing. If you choose to take advantage of this offer and cancel your transfer, we will permanently reduce your registration, renewal, and transfer pricing. Your new pricing will include $8.95 registrations and renewals along with $7.75 transfer pricing. We DO NOT charge an ICANN fee, as most other registrars do. The new pricing applies to the following TLD’s - .com, .net, .org, .info, .biz, and .us. Just click on “renew domains” below to take advantage of this offer and cancel your transfer. The new pricing will apply to all future registrations and renewals as well, and is effective immediately.

This actually frustrated me even more.  So in order to get the cheaper rate, you have to threaten them to leave.  That's is not a business model that I want to be a part of.  If they can offer that rate, then it should be the normal rate.
