Skype: Unlimited calling from $3 per month, 15% off 12-month plans

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. That's the first such discount we've seen from Skype since May, and it's the lowest price we could find for a 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.)

Of note, to receive calls to your Skype phone, you must sign up for an online number. Subscribers to one of the unlimited plans pay $30 per year; otherwise, it costs $60.
