AdDuplex is now processing coupons and they've decided to start this off with a bang. The coupon is FFP2D and is to be used when advertising on Windows Phone using this service. WP7 has enjoyed bathing in the news that the platform experiences higher CTR (click-through rate) accumulation when compared to competitors.

You must hurry however, since this coupon is only valid for two days.
