No, free domain names are not provided with the Reseller Program. In fact, there is no such thing as a free domain name, since domain registrars have to pay for that domain name to the main domain registry. Therefore, if a service offers a free domain name, then the registration fee for that domain is already included in the price that you will be paying anyway.
In any case, with the Free Reseller account, you will be provided with a free subdomain, which will serve as your default web store address and will look like this: yourstorename.haw.com.pk
