1997 Chevy Cheyenne Spark Plug Wires

Took my truck to one of the local dealers for some brake work. Aside from the brake work they say that it looks as if I have never changed my plugs or wires, which is not really true, although I can't remember the last time they were changed. Here is the question, when I asked how much $ they tell me roughly $200 to change plugs and $300 to change plug wires. I know spark plugs aren't that high but when I ask about the plug wires I'm told they are $200. This is nothing like it used to be when I worked on my own trucks. I told them to just fix the brakes and ABS system. What has happened to make plugs and wires a $500 job? I'm thinking I need to start working on my own vehicles again.
