It asks me to verify my credit cart. How much $s I have to load to my credit cart from my bank account for that?
(Note: When I'm going to shop on internet, and lets say there is something for 3.90$ I load 4$ to my credit cart then I proceed to shopping. There lefts 0.10$ and I'm reloading 0.10$ from my credit to my bank account so that no one will be able to get that 0.10$ even if they know my credit cart information, coz you know it is emty now.)
Facebook will not charge your credit card if you add it to your account.. http://developers.facebook.com/blog/post/386/
