Its confusing for anyone, seller or buyer. And if it confuses buyers, sellers wont use it.

I still don't really get how to use it after reading the site and your explanations. Why is there a P vs Q graph? What does paying a fee upfront entitle me to? What is a reservation and what does it give me?

I'm a first time consumer, and you've just thrown a complicated buying method at me, with a graph, current price/lowest price, for which I have no clue how to follow. I think it needs to be bared down to the minimal information necessary.
