I bought the skypeout and skypein package when it was on sale early in the year.
I think it was 19 bucks for unlimited calls out in the United States, now its like 30 I think, check their website.
I also got the skypein local phone number, was like 35 bucks for the year.
So about 55 bucks for the year for unlimited phone calls, about 4.50 per month.
