Note: Some regions and countries may be different but this should work anywhere, unless otherwise stated.
OPTION 1 (All REGIONS )
[spoiler]You can use the recently launched Playstation Store for web browsers, and check out with PayPal directly or add funds to your wallet.
Information on it here: http://wololo.net/2012/12/11/sony-opens ... -webstore/
Sony PSN webstore:https://store.sonyentertainmentnetwork.com/#!/[/spoiler]
OPTION 2 (Most Countries)
[spoiler]*Note:Using PSvita in this example, also some regions and countries may be different but this should work anywhere. You'll need a PayPal card which you can get for free from PayPal for option 1. A PayPal card is just a card that you can use to make purchases anywhere with what money you have in your account. You can get one in your Paypal account settings or here: https://www.paypal.com/webapps/mpp/debit-card
Start up the Playstation Store and click the bottom right button
Hit billing Information
Now enter your paypal card information but with it set to "Master Card" and make sure the rest of your information is up to date (Yes PayPal can work as a MasterCard!)
Back out and hit "Add Funds to Wallet" when you are ready to buy something
Add how much you want by taping the button
Confirm your information, and then tap "Add funds"
Thats it, you are all done! [/spoiler]
OPTION 3 (UK/EU)
[spoiler]Step 1: If you live in UK or EU, sign in to SEN (Sony Entertainment Network) via your pc. I will use the UK for example.
Step 2: Then go to account settings, then go to wallet.
Step 3: Then go to add funds and then it will ask you to select a payment option, select the paypal option.
Step 4: Then select the amount you want from the drop down list i.e (£5, £10) etc,and then it will take you to paypal to sign in and make the transaction.
Step 5: The funds appear instantly in your wallet and you do not need to register your debit/credit card on your SEN account.[/spoiler]
OPTION 4 (VARIES FOR REGION, USE THESE SITES OTHER THAN BESTBUY AT YOUR OWN DISCRETION)
