Type PLAY.STATION3 to log in. This is the official playstation 'rewards' site for members of Royal Mail, Barclays etc.. The site is owned by Centresoft, the UK PS3 distributor.
When you click on it to buy it it'll come up as Playstation 3 Entertainment Pack rather than adding all 3 items. Look at the description in the basket and it includes everything.
The access key is PLAY.STATION3
