i just looked that site up, it looks quite nice, more attractive then ebay.
I think in the next 5 years this online auction market will become alot more fierce then its been with ebay rulling, i think that ebay will have quite a bit of there market share taken come 2013-15.
It seems that this is commission driven. Which is good because you can promote products at no startup cost to you. But bad because you can't sell your own unique product.
