Credit for your PSN,
Verified Purchase(What is this?)
This review is from: Sony PlayStation Network Card - £35 (PlayStation Vita/PS3) (Accessory)
Considering that Sony was hacked in the last 12 months or so, I much prefer this safer form of PSN Store credit, This way i don't have to enter credit/debit card details. As for the credit amount, there are loads of PS Store items to spend it on, such as downloadable games for PS Vita, PS3, PS4. There are always Season Passes for extra game content, including map packs. There are also a few titles that require monthly subscriptions, including the forthcoming Elder Scrolls Online for PS4.
