Vonage is offering a 20% discount and unlimited calling to current customers if you signup for a full year of service.
In an effort to stay competitive with the smaller VOIP providers, Vonage is offering a one year, pre-paid plan, for $239.99 or about $20/month for unlimited local and long distance calling. This saves you $59 over a year.
Vonage sent this notice through their monthly newsletter, available to subscribers. The offer ends March 31st and is open to current customers only.
SunRocket still offers the lowest year-long calling plan for $199 and will refund you for the unused months if you decide to cancel; Vonage does not.
