At first I thought the blog adds some value, as submitting the App Store directly doesn't give as much information... But actually their links all go to themselves. The Popcap homepage has a popup and banner about the sale and donation, so that would suffice for a submission I think. I would say this is HN suitable though, it's interesting to see a game developer giving all proceeds to a worthy cause and slash the price too.
