1and1 launched a promotion that allows you to register .com domains with just $ 0.99 or € 0.70 for the first year, payment accepted with paypal verified account and credit card.
Each customer can register unlimited domains and also offer private whois, the date limit of the promotion is unsure so the best is to register while you can, but according to some sources (unofficial) will be valid only for this month (september 2011).
The major disadvantage of this company is the time it takes to register a domain there, while the large registrars takes only minutes, this can take between 24 to 48 hours, after enjoying this price you can transfer your domain after 60 days and be able to renew your domain for a more affordable price, in 1and1 the second year will cost $ 9.99, and other registrars are doing it for less.
Even so, and by less than 1 € to have a .com domain is an excellent promotion. Register yours now.
