Ways to buy from PSN

Well i know the credit card is the most common way people use for PSN, but they don't allow my credit card for some reason... are there other ways to buy games and add-ons from PSN, i know Prepaid Credit Cards and Virtual Cards, but i once heard that there was something u buy from Best Buy or some other Store which u can easily use. And i just want to know does anyone have a Virtual Credit Card by Trucard? Just want to know if its safe or not.

Thanks in Advance...

All I know is that they accept 2 different ways.

Prepaid psn card

Credit - visa, mastercard, amex

If u think its worthless crap why the hell are u interested on posting, some people just like to waste their time... omg.

Thank You Guys
