Update: They’re gone. Enjoy your new copies of Instapaper Pro, everyone!
I have 37 spare promo codes for the Instapaper Pro 1.3 iPhone app to use before 1.4’s approved. Who wants one? Email imshamelesslycheap@marco.org (really).
To use one, go to “Redeem” in the iTunes Store (front page, right side, “Quick Links”).
