How do these web hosts provide Free Domain Reseller Account? Some also provide WHMCS but I guess it costs around $8 since they purchase in bulk and the cost is already in the packages which they offer. But I might be wrong about the WHMCS thing.
Also if you are a webhost or have deep knowledge about it what uncommon free facility do you offer? [Please do not write in a promotional language since that might get you a infraction.]
