Agreed - at this point it's nothing more than a every so often flash sale with a name your own price system. Not that that's necessarily a bad thing - but I have far less interest in donating larger amounts "to support the community" when it's becoming a deal site - instead I am starting to get the mentality to get everything at the greatest deal I possibly can.
Your post made me realize something. Just like you, I'd previously been generous in my payment to "support the community". When I loaded up the page today and saw the offering, I mentally said "I don't have $20 to blow on this right now" and left the site. Until I read your post, I never even considered that I could just pay less than $20.
Even odder, once I finish writing this, I'm still not heading over there to buy the bundle, even though I could only spend $0.01.
