One of the guys I work with does game design as a hobby. (Joe Huber, first published game Scream Machine by Jolly Roger Games) He buys poker decks in bulk from BJs and prints out stickers that cover the face of the cards. If the game uses a board, he usually just hand draws one on card stock. He's also purchased parts from the local science museum or used parts from widely available board games, i.e. money/markers from Monopoly, etc.
It should be noted that these are prototypes and he's usually not making more than one copy of these games.
