Sorry you feel that way, it's not misleading at all... I purchased a casino related domain name for $20 USD and sold it for $4500 USD within the week. Since I can't discuss that sale, I can tell you about another sale that I used the same exact strategy with. To answer your question, yes; you pay a registrar like GoDaddy $8 - $15 USD annually to retain possession of your domain. This does not include acquisition price. Some domains have a floor price of hundreds of thousands, and some you couldn't give away.
