Erdinc: I have tried to explain things to the OP and other newbies that may read this thread. I am sorry that you bought into one of those reseller plans that requires a large initial investment when you didn't understand what it was.
Domain reselling accounts are for those that either want to try and save money by getting lower prices or who want to have a business where they can selling hosting, domain registrations, transfers, and renewals and make some money doing it. No, it is not needed to buy and sell domains. But since so many people don't make any money with domains when they start, it may help someone get started with domaining as they learn about the business. If you can sell 7 domains and make $1 on each one, then you should have enough to buy a domain that you want.
Dynadot is great, but it's not a reseller account. If someone wants to make money selling domains, hosting, and other services reseller accounts can be a nice way to do that rather than becoming a real registrar.

And in some cases you may pay less than you would at other places for the domains YOU want to buy. True you cannot mark up the prices too much and expect to sell much, but some sites like DirectNIC charge $15 and manage to stay in business...!
As far as if my information confuses anyone, I think they can speak for themselves about that. I am willing to keep answering questions until they understand all of their options. If I can help someone keep from making the mistake you did, or signing up for a plan that costs $50-$100 a month I think it's worth the time I spend...
The clear lesson here is if you are going to buy domains or become a reseller, make sure you KNOW what you are getting into before unless you want to take risks and waste money.
