Just sign up for their deal flyer by typing your email address into whereever it is on their site to sign up for the dealflyer and you'll get a couple emails a week letting you know that you have a discount for anything from 20% to sometimes 40% off even over whatever their current discounted price is.
I never have used precip. I went from Impertech (heavy) to gore-tex pro shells (expensive and still didn't breath all that well) to eVent (light, breathes well, and not as expensive as gore-tex pro shells.) But I still use impertech for motorized based hunts.
