Rules of Thumb-Domain Transfer

[Frankie]

Hey all,

I have been registering all my domains with Go Daddy. I am in the process of selling a few, and wanted to know if their were any rules of thumb when transferring domains between registars?
I have heard their is a cost involved. Who should pay the fee--the seller or buyer (or both)?
Is this something you should include in the sale price?
Is their anything else I should know that could bit me in the butt?
Thanks

I'd probably say something like "transfer costs to be paid by buyer" - the buyer may want to change registrars, for example, and this way you'll be covered.
