PlayStation Network codes are available to purchase from retailers such as Amazon.com and Wal-Mart. Gamers redeem these codes for games, music, movies and TV shows on PSN.
Players fill their virtual wallets with the money they get from entering PSN codes and use that money to not only buy games but also downloadable content for the games they already own. This includes additional maps, new characters or exclusive missions.
Sony offers millions of videos, shows and songs on PSN. Players have the option to buy movies or rent them for a day. They can also watch those videos or listen to songs on Sony devices such as the PS3, PS4 or Vita.
