This is not really about coupons.
You could drive past the same plumber's billboard every morning and every night for a year and barely notice it.
Then one day a pipe bursts. You walk outside, see that billboard, and think, "Oh yeah. I need a plumber."
That is what we are doing here. We are helping people around Redmond see your name often enough that, when they need what you do, you are one of the first businesses that comes to mind.
