I thought perhaps something like this.
"Times are hard and there is currently an upsurge in a new breed of window cleaner offering services for less,almost a "dirty arab spring",so to speak.This is driving prices down and on reflection my own pricing stucture will not remain competitive.Wishing always to be at the forefront and cutting edge of this industry i shall be reducing my prices by 15% forthwith.No further price reductions are intended for at least 12 months."
However I`m not sure if i would be doing this for the customers benefit or mine.
Should i just reduce the price and say nothing?
