Skype.com is again offering their unlimited calling plans from at $2.99 per month. You can also sign up for a 12-month plan to get 15% off, dropping the monthly rate to $2.54 per month at checkout. At $30.48 for the year, that's tied with the lowest price we've seen this year for VoIP service, which had not resurfaced since January. The base plan includes unlimited calls to the US and Canada, and you can also sign up to get unlimited calls to individual countries for $7.99, or you can get a plan that allows for unlimited calls to 40 countries for $13.99 when you sign up for 12 months. You will have to sign up for an online number to use Skype.
