Easy way of buying things without entering your credit card info in the PS Network, if you're concern about it. I seldom buy this, but every time I do, it's for my personal use. But it is a great idea as a gift, and it can be very welcome.
This was excellent! You see, I'm in New Zealand and until now I have only had access to the New Zealand PSN store. There are many games available on the US PSN store that aren't available in New Zealand. So, I signed up a new PSN account with the US PSN store and bought this PSN card through Amazon so that I could load US currency into my US PSN account, and then I was able to buy a game that I've wanted for ages through the US PSN store that is not available in New Zealand. Very very happy! :-)
