If you need a credit card as I do, to rent a car also for plane tickets and what not, for example requires a credit card not a debit card. Sony has a visa card with no annual cost to have. Also when you make your first purchase no matter what it may be gas for the car ect. within a few days you will get an email on how to get a redeem code for $50 psn credit. You also get 10X reward points on sony products ect. So if you are needing or thinking of getting a credit card this is not a bad deal. However be wary, and don't go apeshit with the plastic money. Because just at that moment you don't have to pay cash, one day very soon the bill will be in the mail. Also if you are a responseable person and don't max the card out, it is a great way to improve your credit score if you use common sense.
