Josh Freese, former drummer for Nine Inch Nails has come up with an innovative take on "pay what you want". For $7, you can download his new album. For $50, you get the album and a "thank you" phone call. For $1,000 you get the album and he'll come over to do your laundry. The entire list is hilarious and worth reading, check it out here.
This was partially a publicity stunt, but the idea of having multiple price points is a good one. Businesses do this all the time -- it's called merchandising.
