Im new here, since I dont have my gaming pc available right now, and I cant take my ps3 with me everywhere I joined this place to get some cheap games while my pc is fixed.

Can someone please give me some links to tutorials on how to download these games that are sold on here to my ps3?? I got a pretty good idea how it all works from using mspoints accounts on my xbox360, but would love any help I can get, thanks.
