highway robbery

I had a plumber come today to fix a leaky faucet. While he was here I asked him to take a peak at the brown spots on my lawn and see how much it would cost to fix my sprinklers. He crunched some numbers and came back with a bid of $755.00 to fix the three broken sprinklers. Gulp. I said I'd talk to my husband and get back to him. Inspired by what seemed like an insanely high bid I channeled my inner DIY-er and consulted the world wide web. Found this little ditty, stopped by Home Depot, and 2 hrs later I had fixed four (I found another broken one) sprinklers. I called the plumber back to make sure I hadn't read the bid wrong and he really quoted me $155. No ma'am: $755.
