I stumbled upon their site few days ago, and it seems that it's just recently launched. I've learnt some blogs talked about it, but hey, great things are always meant to be conversation pieces :). Supermarket (US) works just like Bouf (UK), where shoppers could buy great things direct from designers. Tons of cool products there, you could check them all out here. And if you think you have cool things to sell, you could let them know here. And oh, they have a cool blog, too. Super!
