I just had an email about this and thought although there was a post over a year ago relating to this that its worth a repost
Making free Skype-to-Skype calls is great. But did you know you can use Skype to call landlines and mobiles at great, low cost rates as well?
For instance, you can get unlimited calls to landlines* with one of our monthly subscriptions. You can choose just one country (even your own), a region or more than 40 countries worldwide. Prices start from just 3.39 GBP / 4.54 EUR / 6.85 USD per month.
Works out a really cheap deal, maybe those who use it can give me some feedback on it as to whether its got any catches.
I read it though and i cant seem to see any bad points?
