I'm winning a plane for 10 billion dollars.
Layout is great, except for where you bid...it took me about 30 seconds to find out where that was. Perhaps having it bold IMPACT or at the top or bottom rather than in the middle in small font.
Other than that it looks great, but will there be charges similar to e-bay? i.e. pay $0.60 cents to post an ad or ads with lots of pictures, fancy font, etc.
