The recently launched PopDeal is a web service that coalesces social media and shopping. Users can submit items, in this case links to online deals (mostly gadgets and computer hardware), and vote them up or down all in a simple, Reddit style interface. Popular deals make it to the homepage, just as with digg.

PopDeal is still gaining momentum and will take a while for it to get to SlickDeals status if it catches on. Similar social shopping sites include CrowdStorm and Wize.
