After being so frustrated that you can buy the game for like 15GPB, but can't import, I finally found this over at CAG.
EDIT: the cheapest I can find the US version is $45, so I bought the $20 uk version
*UPDATE*: I got my game about 4 days after I bought it
I am proud to announce that on April 13th, 2009, we will be celebrating the one year anniversary of the opening of GameDealDaily.com.
We are very thankful for all of our customers and especially to CAGs, as many of them have supported our website over our first year in existance.
As a thank you to all of our customers, we will be running a sale on LittleBigPlanet for Playstation 3 from March 6th until our year anniversary on April 13th. The game will be available for $19.95, brand new.
This is a PAL version PS3 game. Playstation 3 games are not region-locked. Therefore, you will be able to play the PAL PS3 games perfectly on your American PS3 system. Online play in LittleBigPlanet is also region-free, so you will be able to play online against American players. The only difference is revealed when you want to download content from Playstation Network for the game. To do this with a PAL PS3 game, you will need to create a European PSN account to access the DLC. Anyone can do this, and it is not difficult.
We have this game in-hand, and all orders will begin to ship out on Monday.
