Other than the adwords vouchers, the features you listed are worthless. You can point the domain to your own hosting account and show a "for sale" page / install WP / add email accounts / whatever.
Worthless? Alot of companies charge extra for what we supply free. How about $1.99 domains? Ulimited amount you can buy for that price with an extra product purchased. Like I said before. Some people do not like the competition.
Didn't realise you were promoting your service I never said $1.99 domains weren't a nice offer, I just said the perks I quoted don't bring any real value for the extra bucks you're charging. Most seasoned webmasters are enough tech-savvy not to need free site generators, domain-for-sale pages and email forwarders.
Namecheap is good and they offer free whoisguard to shield your private information. In my experience Godaddy has limited features
