Calling card offer

There is a calling card site known as stanacard.com, this allows users to double the amount of their first time buying. So for eg:- you buy a credit of $20, first time alone it will be doubled and you will get $40 worth of calling credit. But you will need a promotion code while you signup.
I got this from my friend. I tried this personally and voice quality is good.

You can search in google as "stanacard coupon codes" and can get lot of codes. For calling india it is 7.8 cents per minute( i don't know about other countries). Also you get double the credit, so it is cheap.
