I didn't read through all of the replies in this thread, sorry, so maybe this has been pointed out already BUT:
I recently made the groundbreaking discovery that the parchmentpaper that comes with the P3-product can easily be rinsed off and used multiple times. I went through the papers at a very high pace, and when I came to the last paper I found this out. I think I have rinsed it off maybe 10 times, scrubbing it gently while I'm rinsing. My wallet is forever thankful.
