godaddy gives one via west wild domains. I have been contracting from them for 2 years already. If you click on my signature in danthra domains, your will see the front end they provide. Basic service to sell domains, $99 a year, with affiliate $199, a year. Sandra.
If you are looking for a domain reseller program with no annual fees and best support then checkcout http://reseller.directdot.com great low prices, best support. If you are looking for the Reseller Proram that Godaddy offers, then check out http://www.winkdomains.com/reseller to save on Godaddy Reseller Plans they start for basic @ $59.99 and the Pro reseller @ 159.99
The only company that really does that is with a Directi, or Enom even. I believe they let you resell resellers.
Then there are few options to choose from Go directly to a registrar and find if they have programs that allows you to resell to resellers. such as wild west domains 'Godaddy sister company' - look for their super reseller program. (there is an annual fee $229.00) I have a super reseller account myself with them. Directi ResellerClub - your cost is depnding on howmuch you spend with them. to get the lowest pricing you must deposit a good chunk of money. DirectDot reseller program offers the same program as ResellerClub without making huge investment, you can also have sub resellers under your account and your sub can have subs as well. I am not sure about eNom haven't done business with them, yet let me know if you have questions Good luck,
