When You Buy a Full Game in Playstation Network, Will They Deliver You the Game or You Download It?

Im Just Curious Because I have A PS3 SLIM. And i want to know about buying full games in playstation network.

Suggestion:

You just have to download the game but if you deleted the full game just go to the PSN store and go to View Downloads in the top right corner and select it from the lost. I believe you can re-download what you bought 4 times without having to pay again.
