I heard from a little birdie that if you are with a higher price registrar and you call and say you are transfering away from them because you have found a cheaper registrar, they will give you a special deal and match the price of the cheaper registrar. Try it out the next time your domain comes up for renewal!

depends on the registar/register if you tell them you can get them for 6.49 they will tell you bye bye if they are selling them at 8.88 unless you have over 1k or 2k and if you are dealing with those numbers you should be at your 6.* ish price range anyways
