Dean, I think that's a great idea and I'd check back regularly to see what's up for grabs!
As far as the limiting the number of people to buy tix, that's iffy with me. How can you donate 25% to the CEG board if you limit it to the price of the product? Maybe limit it to the price of the product and 25% or something.
As far as allowing people to buy more than one ticket maybe try one of each and see how they work out or limit their share to a certain percentage of the total # of tix sold.
