Skype.com offers its unlimited calling plans starting at $2.99 per month. Or, sign up for a 12-month plan to get 15% off and drop the monthly rate to $2.54 per month. (The discount appears during checkout.) That's tied with our mention from two weeks ago as the lowest price we could find for VoIP service of this kind. The base plan allows you to make unlimited calls to any phone within the US and Canada from your Skype phone. Unlimited calls to individual countries or over 40 countries cost $7.99 and $13.99, respectively. (The 15% off discount also applies to these plans when you sign up for 12 months.)
