Can I add Funds by going online on my PC instead on my PS3? It just seems very complicated to do on my PS3. If so, were exactly, is there a link?
Welcome to the Playstation Online Community.
If you're having trouble try using the Qriocity website to add your funds, here's the link: http://www.qriocity.com/us/en/
To add funds for a credit card, see PS3 User Guide: Using the wallet.
To redeem PSN cards, see PS3 User Guide: Redeem Codes.
You can also use Sony's Media Go software to add funds. The software is designed for use with handheld consoles and mobile phones; but the same PSN wallet is used regardless of console, so if you add funds in Media Go, you can use them on any Playstation Store interface. The interface itself is largely the same regardless of where you do it though. You can add funds right in the Playstation Store interface, and that looks and works about the same wherever you use it.
