Yes Skins mentioned a while back that their shoes would be sold through Zappos. The product page was created, but no shoes were ever sold. I THINK they did list some Skins shoes for a while, but then they disappeared.
I'm not sure what will happen with this acquisition. I don't know if Zappos inventory will be integrated into Amazon, or Amazon's inventory will be integrated into Zappos. Either way, it can't hurt Skins. Not sure if it will be an overwhelming help, but it can't hurt.
Last I read, the acquisition was supposed to be finalized in the fall. They see nothing to stop it, but because Amazon is a public company, it has to go through approvals before the deal is finalized and the products of each are combined.
