Skype, the world’s most popular internet video chatting program, is currently giving away a full month of video calls to new and current customers for free. But the offer is only on today, and it does come with a few caveats. Namely, you must enter a valid payment option that will be charged at the end of the month. You can always make sure to cancel at the last minute, but if you forget, you’ll be charged for another month’s worth of service for $13.99. Additionally, while the Skype service allows you to make calls to people’s cell phones in seven countries and landlines in over forty countries, the offer does exclude special, premium and non-geographic numbers.

The move likely comes Following Microsoft’s acquisition of the company earlier this fall, the company is hoping to bring some new users into the fold in a way similar to how they’re offering Office 365 University to students at specialized rates that also just happen to include a free month of Skype. Not that I’m complaining, of course.

So, whether you’re a current user or not, follow this link to Skype’s site to get a month of the service for free.
