People who buy nintendo products which require one or more other nintendo products are a fine example.
"So I can buy this playstation 2 that doesn't come with a hard drive, but to play the latest Final Fantasy, I have actually do have to buy a PS2 hard drive and a network adapter in addition to the $200 I paid for the PS2? Wow, I sure am a consumer whore."
"Not only will they have to pay $80 to buy this MMO computer game, but they will have to pay an additional $15 a month to continue playing it! The 5 servers our company bought to run this game will pay for themselves in 2 weeks! Thank god for comsumer whores!"
