Yup 1 and 1 hosting/domain service provider offers Private Registration With $5.99 Domains. 1&1’s new plan is stilll priced at $5.99 for a one-year .com registration, but will now include private domain registration, a feature that is a paid add-on at other providers. The enhanced plans also include a 1 gigabyte e-mail account and a web starter page at no additional cost. Now how cool is this?
Yup you will not get those spam email and your private information remains safe. But it is not a limited-time promotion and bundled with standard domain package. :D
