How can I get GT: HD Concept and/or the GT 5: Prologue Demo?

Hey everyone, I just got my PS3 a week ago and I was wondering how I can get the Gran Turismo: HD Conecpt demo and/or the GT 5: Prologue Demo.

Is there any way I can get either of these items?

Thanks

I dont even think you can download GT Concept anymore. Get Prologue :).

GTHD is on PSN and GT5P demo was on the *** market place but a long time ago. i still got my demo. haha. the full version is out to buy now.

Are you sure GT: HD Concept is in the PS Store?

Because I checked and the only thing in the PS Store related to Gran Turismo is GT 5: Prologue.
