Ps3 helppppppppppppppppppppp?

You pretty much have to add funds to your wallet to buy anything off the PlayStation Store. You can get voucher codes from various gaming companies for a free download of something, but you don't see those very often. There's a few things you can doto get an invite to play a games beta. Sometimes if you preorder a game you get an invite like MGS4. Sometimes the game developers will ask people to sign up on the games website to get in like COD WaW. Also if you register evrything you buy on the PlayStaion Underground, you increase your chance of getting into closed to the public betas like Home.
