Usually, I just add funds directly from my credit card if I want to purchase games/items from PSN Store. But since I am currently not in US, the PSN rejected my request to add funds directly. Plus, retailers in my country are selling the PSN cards at much higher price (about 60% higher! can you believe that??). Therefore this situation kinda turn me into a sad panda.

Then I discovered this service.

I purchased the card, get the code and immediately entered it...BANG! It works! You don't know how happy I am that I can finally purchase games/add-ons that I want

Okay sorry for the exaggeration. Nevertheless, thank you Sony for providing this service! It's nice to add different ways to add funds to our PSN wallet.
