This is an awesome deal from Network Solutions. You can grab up to 5 domain names (.COM, .NET, .ORG, .INFO or .BIZ) for only $1.00 each!
No coupon code needed, just follow the link above to avail of this promotion.
The only downside is that the renewal fee is $38 per year, which is way more expensive than most registrars, but still this offer is attractive enough because of the cheap price.
The offer price does not include domain privacy, which costs an additional $9.99 per year. You can pay using Paypal or credit card.
